* lisp/vc/vc-git.el (vc-git--pushpull): Make `extra-args' a list.
Do not set `compilation-error-regexp-alist', this is done in
`vc-compilation-mode'.
(vc-git-error-regexp-alist): Tweak the regexp.
* lisp/vc/vc-hg.el (vc-hg-error-regexp-alist): Make non-trivial.
(vc-hg--pushpull): Accept `post-processing' argument.
Call them after the `command'.
(vc-hg-pull): Pass the `post-processing' commands that show which
are to be modified by the `update', and then run `update'.
* lisp/vc/vc-git.el (vc-git--pushpull): Accept extra-args and set
`compilation-error-regexp-alist' to `vc-git-error-regexp-alist'.
(vc-git-pull): Pass "--stat" as `extra-args' to `vc-git--pushpull'.
(vc-git-push): Pass "" as `extra-args' to `vc-git--pushpull'.
* lisp/vc/smerge-mode.el (smerge--refine-chopup-region): Use
utf-8-emacs-unix, not emacs-internal, to make the forced EOL
convention explicit.
(smerge-refine-regions): Use utf-8-emacs instead of
emacs-internal, to allow decoding of non-Unix EOL conventions.
(Bug#29916)
* lisp/progmodes/grep.el (lgrep, rgrep, grep-read-files): Explain
how to enter whitespace when using grep-read-files. (Bug#29303)
* lisp/progmodes/project.el (project-find-regexp): Likewise.
* lisp/vc/vc-git.el (vc-git-grep): Likewise.
Add a do-nothing implementation for vc-rcs to suppress the message which
the default function adds to the vc-dir buffer (Bug#28570).
* lisp/vc/vc-rcs.el (vc-rcs-dir-extra-headers): New function.
This fixes some URLs I omitted from my previous pass,
notably those in lists.gnu.org. Although lists.gnu.org
does not yet support TLS 1.1, TLS 1.0 is better than nothing.
* lisp/erc/erc.el (erc-official-location):
* lisp/mail/emacsbug.el (report-emacs-bug):
Use https:, not http:.
* lisp/vc/vc-hooks.el (vc-prefix-map):
Bind `vc-region-history' to 'C-x v h', which was earlier bound to
`vc-insert-headers' (Bug#27644).
* doc/emacs/maintaining.texi (VC Change Log): Mention the new binding.
* doc/emacs/vc1-xtra.texi (Version Headers): Remove the association of
'C-x v h' with `vc-insert-headers'.
(http://lists.gnu.org/archive/html/emacs-devel/2017-09/msg00957.html)
* lisp/vc/vc-hg.el (vc-hg--pcre-to-elisp-re)
(vc-hg--slurp-hgignore, vc-hg--read-repo-requirements)
(vc-hg-state-fast): Use file-name-absolute-p and directory-name-p
instead of relying on Unix file-name syntax. This avoids
assertion violations on MS-Windows.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
* lisp/vc/diff-mode.el (diff-find-file-name): Save the current
narrowing, and widen the buffer before searching for the name of the
file corresponding to the diff.
With thanks to Noam Postavsky.
This regexp contains "\\|", thus a concatenation
of "^" with it just matches the beginning of line for the
first alternative in diff-file-junk-re.
* lisp/vc/ediff-ptch.el (ediff-map-patch-buffer): Concat "^" with
diff-file-junk-re wrapped in a shy group.
