Since 'eshell-named-command-hook' already makes execution of commands
extensible, "which" should be too. This makes sure that "which" returns
the right result for quoted commands like "/:cat".

This allows for other output targets (see the following commit) to be
"line-oriented".
* lisp/eshell/esh-io.el (eshell-ensure-newline-p): Move from esh-cmd.el.
(eshell-target-line-oriented-p, eshell--output-maybe-n)
(eshell-print-maybe-n, eshell-error-maybe-n)
(eshell-maybe-output-newline): New functions.
* lisp/eshell/esh-cmd.el (eshell-lisp-command): Don't print a newline
in this function directly; instead, use 'eshell-print-maybe-n' and
'eshell-error-maybe-n'.
(eshell-ensure-newline-p): Move to esh-io.el.
* lisp/eshell/em-unix.el (eshell/cat): Remove now-unnecessary override
of 'eshell-ensure-newline-p'.
This was documented to work by calling the output function with 'nil',
but that was never actually implemented. Instead, for compatibility,
we now support a new (optional) close function.
* lisp/eshell/esh-io.el (eshell-virtual-targets): Update docstring.
(eshell-generic-target): New struct...
(eshell-function-target): ... inherit from it, and rename from

This also adds the ability to suppress module loading/unloading
messages, which will be necessary to support running Eshell scripts as
batch scripts.
* lisp/eshell/esh-mode.el (eshell-mode): Move module
loading/initialization to...
* lisp/eshell/esh-module.el (eshell-load-modules)

history for minibuffer.
(eshell-add-command-to-history): Immediately save history.
We have not been able to discover why these functions let-bound
`inhibit-modification-hooks`, but these let-bindings are
undesired effects on other modes such as `diff-mode` which
need to keep track of buffer modifications. Let's remove those
let-bindings and hope for the best.
* lisp/eshell/esh-mode.el (eshell-send-input)
(eshell-interactive-filter): Don't bind `inhibit-modification-hooks`.

Erase all existing duplicates instead of just the last duplicate entry
when 'eshell-hist-ignoredups' is set to 'erase'. Multiple duplicates
can exist in case 'eshell-hist-ignoredups' was set to something else
than 'erase' in the past or if the history file contains duplicates
(bug#71107).
* lisp/eshell/em-hist.el (eshell-add-input-to-history): Remove all
duplicates from history ring.

(em-glob-test/convert/quoted-start-directory): New test.
* lisp/eshell/em-glob.el (eshell-glob-convert): Use 'concat' instead of

directory possible.

* test/lisp/eshell/esh-opt-tests.el (esh-opt-test/process-args):
(esh-opt-test/process-args-parse-leading-options-only):
(esh-opt-test/process-args-external): Pass OPTION-SYMS in.
Normally, "echo<RET>" runs the command "echo". Likewise,
"echo\<RET><RET>" should too: we escape the first newline, and then
the second one is unescaped and should send the command input to
Eshell. Previously, you had to press RET a third time, but now it
works as expected.
* lisp/eshell/esh-arg.el (eshell-looking-at-backslash-return): Make
obsolete.
(eshell-parse-backslash): A backslash sequence is only incomplete if
there's nothing at all after it.
* test/lisp/eshell/esh-arg-tests.el (esh-arg-test/escape/newline)
(esh-arg-test/escape-quoted/newline): Remove inaccurate comment;
escaped newlines are always special.
(esh-arg-test/escape/trailing-newline): New test.
This is particularly important when the inner command to execute is an
alias. Aliases throw 'eshell-replace-command' too, so we want to do
this in two phases: first, replace the "sudo"/"doas" with a
let-binding of 'default-directory', and then later, let the alias code
do its own replacement (bug#68074).
* lisp/eshell/em-tramp.el (eshell/sudo, eshell/doas): Use
'eshell-replace-command' to wrap the inner command.
* test/lisp/eshell/em-tramp-tests.el (mock-eshell-named-command):
Remove.
(em-tramp-test/sudo-basic, em-tramp-test/sudo-user)
(em-tramp-test/doas-basic, em-tramp-test/doas-user): Catch
'eshell-replace-command'.
I think this regressed partly due to eef32d13da, so let's add some
regression tests to make sure that doesn't happen again.
* lisp/eshell/em-unix.el (eshell-unix-initialize): Add "compile".
* lisp/eshell/esh-cmd.el (eshell--find-subcommands): Yield the second
element of the subcommand.
(eshell--invoke-command-directly-p): Rename and account for
'eshell-with-copied-handles'.
(eshell-invoke-directly): Rename to...
(eshell-invoke-directly-p): ... this, and use 'pcase' to make the
logic clearer.
* lisp/eshell/esh-mode.el (eshell-send-input): Always queue input if
the process is running; rename some locals to be clearer.
* lisp/eshell/esh-var.el (eshell-var-initialize): Add "env" as a
complex command.

(esh-var-test/local-variables/env): New test.
* doc/misc/eshell.texi (Built-ins): Describe the new behavior.
* etc/NEWS: Announce this change.
This ensures that these commands work the same as normal commands,
aside from making environment variable settings local to that command.
Among other things, this means that "VAR=value cd dir/" now changes
the directory correctly.
* lisp/eshell/esh-var.el (eshell-in-local-scope-p)
(eshell-local-variable-bindings): New variables.
(eshell-var-initialize, eshell-set-variable): Use
'eshell-local-variable-bindings'.
(eshell-handle-local-variables): Don't use 'eshell-as-subcommand'.
* test/lisp/eshell/esh-var-tests.el (esh-var-test/local-variables/cd):
New test.
* lisp/eshell/em-hist.el (eshell-history-append): New option.
(eshell--save-history): New function.
(eshell-hist-initialize):
(eshell-save-some-history): Replace eshell-write-history with
eshell--save-history, which respects the new option.
* doc/misc/eshell.texi (History): Document the change.
* etc/NEWS: Announce the change. (Bug#66700)
* lisp/eshell/esh-proc.el (eshell-gather-process-output): Get the
local part of the $PATH (bug#67126).
Do not merge to master.
Copyright-paperwork-exempt: yes
* lisp/eshell/em-hist.el (eshell-hist--new-items): New variable.
(eshell-hist-initialize): Initialize 'eshell-hist--new-items' to 0.

history in current buffer to history file". Clarify the help text of
'history -r'.

(eshell-read-history): Respect 'eshell-hist-ignoredups' option.
(eshell-write-history): If the optional argument APPEND is non-nil,
appending new history items rather than the whole history.
* test/lisp/eshell/em-hist-tests.el (em-hist-test/history-append)
(em-hist-test/history-read): New tests (bug#66768).
