* lisp/textmodes/flyspell.el
(flyspell-check-previous-highlighted-word): Fix off-by-one error when
word is at (point-min). (Bug#39898)
Suggested by OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>.
* lisp/pcmpl-linux.el: Use lexical-binding.
(pcmpl-linux-fs-modules-path-format)
(pcmpl-linux-mtab-file): New constants.
(pcmpl-linux-fs-types, pcmpl-linux-mounted-directories): Use above
new constants.
* test/lisp/pcmpl-linux-resources/fs/ext4/.keep:
* test/lisp/pcmpl-linux-resources/mtab:
* test/lisp/pcmpl-linux-tests.el: New files.

4657f08b7e Sync with Tramp 2.4.5-pre
* lisp/mail/qp.el (quoted-printable-encode-region): If we're in a
multibyte buffer (that has been encoded with some coding system),
then get-byte will get the correct byte value.
* src/alloc.c (mark_maybe_object, mark_maybe_objects): Remove.
(mark_objects): New function.
* src/eval.c (mark_specpdl): Use mark_objects instead of
mark_maybe_objects, since the array now has only valid Lisp objects.
* src/lisp.h (SAFE_ALLOCA_LISP_EXTRA): When allocating a large
array, clear it so that it contains only valid Lisp objects. This
is simpler and safer, and does not hurt performance significantly
on my usual benchmark as the code is executed so rarely.
This lets Emacs avoid marking some garbage as if it were in use.
On one test platform (RHEL 7.8, Intel Xeon Silver 4116) it
sped up ‘cd lisp; make compile-always’ by a bit over 1%.
* src/alloc.c (live_string_holding, live_cons_holding)
(live_symbol_holding, live_large_vector_holding)
(live_small_vector_holding):
Count only pointers that point to a struct component,
or are a tagged pointer to the start of the struct.
Exception: for non-bool-vector pseudovectors,
count any pointer past the header, since it’s too much
of a pain to write code for every pseudovector.
(live_vector_pointer): New function.
* src/alloc.c (mark_memory): Do not bother using mark_maybe_object
on the stack, since mark_maybe_pointer now marks everything that
mark_maybe_object would.
On --with-wide-int platforms where Lisp_Object can be
put into non-adjacent registers, mark_maybe_pointer failed
to mark a float whose only reference was as a tagged pointer.
* src/alloc.c (live_float_holding): New function,
a generalization of the old live_float_p.
(live_float_p): Use it.
(mark_maybe_pointer): Use live_float_holding, not live_float_p.
* lisp/play/life.el (life): New defgroup.
(life-step-time): New defcustom (lower default from 1 to 0.5).
(life): Use above new variable. Make prefix arguments set step time
in tenths of a second instead of whole seconds.
(life-expand-plane-if-needed): Rename argument to step-time.
(life-setup): Fix running `M-x life' with existing buffer.
(life-patterns): Add three more classic patterns.
* lisp/wid-edit.el (file widget): Add a :match and a :validate
function to the 'file widget, to be able to check if the widget
value is an existent file, when required (bug#25678).
Having it placed in the beginning of that hook meant it was mostly
impossible to track the args to a function call while writing it from
scratch, since most compilers issue a diagnostic about incorrect
number of arguments.
See bug#43103.
* lisp/progmodes/flymake.el (flymake-mode): Lower priority of
flymake-eldoc-function.
* doc/lispref/minibuf.texi (Text from Minibuffer): Document it.
* lisp/help-fns.el (describe-function): Adjust the caller.
* lisp/minibuffer.el (format-prompt): Interpret a nil default
value as "no default".
