In particular, this resolves an issue where '$+' referenced the real
environment variable '$PWD' instead of the Eshell variable alias of

When executed like a command, 'list' looks for external programs named
'list' first before falling back to the Lisp function of the same

what we want in these tests.

* lisp/eshell/esh-util.el (eshell-find-delimiter): Correct docstring
and treat '\' as an escapeable character when using backslash escapes.
* test/lisp/eshell/eshell-tests.el
(eshell-test/escape-special-quoted): Adapt test.
* lisp/eshell/em-extpipe.el (em-extpipe--or-with-catch): New macro.
(eshell-parse-external-pipeline): Use new macro to treat
`eshell-incomplete' as a failure of the parse function to move us
forward (Bug#54603). Thanks to Jim Porter <jporterbugs@gmail.com> for
the report and for help isolating the problem.
* test/lisp/eshell/eshell-tests.el
(eshell-test/lisp-command-with-quote): New test for Bug#54603, thanks
to Jim Porter <jporterbugs@gmail.com> (bug#54603).
'em-basic-test/umask-set' fails when passing an actual number to the
command, but this is fixed in the subsequent commit.
test/lisp/eshell/em-basic-tests.el: New file.
* test/lisp/eshell/esh-proc-tests.el (esh-proc-test/kill-pipeline):
Add pattern matching output when killing a process on macOS (and
possibly other BSDs).
For example, '${echo -e "hi\nbye"}[1]' should expand to "bye".
* lisp/eshell/esh-var.el (eshell-parse-variable-ref): Support applying
indices to '${}', '$()', and '$<>' forms.
(Bug#54227)
* lisp/eshell/esh-var-tests.el (esh-var-test/interp-lisp-indices)
(esh-var-test/interp-cmd-indices)
(esh-var-test/interp-cmd-external-indices)
(esh-var-test/quoted-interp-lisp-indices)
(esh-var-test/quoted-interp-cmd-indices): New tests.
