* lisp/progmodes/compile.el: Cleanup text-properties namespace by using
`compilation-message' instead of `message', `compilation-directory'
instead of `directory', and `compilation-debug' instead of `debug'.
(compilation-last-buffer, compilation-parsing-end)
(compilation-error-list, compilation-old-error-list): Move to the
compatibility part of the code.
(compilation-error-properties): If `file' is a function, let it return
a file name.
(compilation-mode-font-lock-keywords): Be more conservative with the
omake "^ *" pattern prefix, to try and minimize the risk of
pathologically slow regexp matching.
(compilation-start): Use inhibit-read-only.
(compilation--unsetup): New function.
(compilation-shell-minor-mode, compilation-minor-mode): Use it.
(compilation-filter): Minor tweaks.

(compilation--flush-file-structure): New fun.
(compilation-fake-loc): Use it for cleaner behavior when file is reused.
(debug-ignored-errors): Add "Moved past last ...".
(compilation--compat-error-properties)
(compilation--compat-parse-errors): Rename by doubling the "-".

* lisp/progmodes/grep.el (grep-regexp-alist): Tighten regexp.
(grep-mode-font-lock-keywords): Remove regexp that seems like
a left-over from before we used compile.el.
(grep-mode-font-lock-keywords): Call syntax-ppss-flush-cache when
modifying the buffer within with-silent-modifications.

* lisp/progmodes/prolog.el (prolog-system): Add GNU and ECLiPSe options.
(prolog-program-name, prolog-program-switches, prolog-consult-string)
(prolog-compile-string, prolog-prompt-regexp): Get rid of the <foo>-i
variable and use a function to compute the value dynamically.
(prolog-prompt-regexp): Add regexp for GNU Prolog.

(prolog-inferior-mode-map): Use it.
(prolog-inferior-error-regexp-alist): New var.

(prolog-input-filter): Use derived-mode-p.
(prolog-inferior-guess-flavor): New function.
(prolog-ensure-process): Use it.  Use make-comint-in-buffer rather than
make-comint to avoid running comint-mode twice.
(prolog-inferior-buffer): New fun.
(prolog-old-process-region, prolog-old-process-file):
Don't call prolog-bsts here...
(prolog-build-prolog-command): ...do it here instead.

* Makefile.in (DOS_gnulib_comp.m4): Renamed from DOS-gnulib-comp.m4,
for portability to POSIX make.  Reported by Bruno Haible.
(sync-from-gnulib): Copy gl-comp.m4 (if present) back to
gnulib-comp.m4 before running gnulib-tool, to prevent old gnulib
files from accumulating as garbage.  Also reported by Bruno Haible.

gnus-group.el (gnus-group-refresh-group): Refresh even non-visible groups.  This makes the nndraft:queue group pop up if it's not already there.

"*server*" which is never created by emacs server.

there are some diff switches.

Miscellaneous cleanup such as:
- Don't hide expressions after a closing paren.
- Move initial setq into let.
- Hoist common parts out of ifs.
(hfy-p-to-face, hfy-p-to-face-lennart): Remove.
(hfy-face-at): Use get-text-property instead.
(hfy-prop-invisible-p): Use invisible-p if available.

(hfy-html-quote-regex): Use [...].
(hfy-combined-face-spec): Simplify.
(hfy-compile-face-map): Don't presume point-min==1.
(hfy-css-name, hfy-buffer, htmlfontify-buffer): Use \' rather than $ to
match end of string.
(hfy-text-p): η-reduce.
(hfy-tags-for-file): Receive cache-hash directly.
(hfy-mark-tag-names): Adjust call.

shr.el (shr-expand-newlines, shr-previous-newline-padding-width): Use plist-get instead of the cl function getf.

shr.el (shr-put-color): Special-case background colours: Do put them at the blank parts at the front of the lines.

(msb-after-load-hook): Remove eval-after-load wackiness.

gnus-art.el (gnus-article-next-page): Change last-line-displayed behaviour.
 (article-lapsed-string): Refactor out and allow specifying how many segments you want.
 (gnus-article-setup-buffer): Start updating the lapsed header directly.
 (gnus-article-update-lapsed-header): New variable.
shr.el (shr-put-color): Don't do the box padding in tables, since they're already padded.
gnus-util.el (float-time): If float-time is bound, always use it on all Emacsen.  It's unclear why the subrp check was there.
 (time-date): Require to make some autoload issues on XEmacs go away.
gnus-draft.el (gnus-draft-clear-marks): New function to be run as an exit hook to nix out all data on readedness on group exit.
gnus-sum.el (gnus-auto-select-subject): Doc typo.

* src/eval.c (maybe_call_debugger): Declare before new use.
(find_handler_clause): Don't call debugger any more.
Ignore Vstack_trace_on_error.
Use XCAR/XCDR.
(syms_of_eval): Remove Vstack_trace_on_error.
(Fsignal): Only modify handlerlist when we know we need to do it.
Call the debugger when necessary.

Fixes: debbugs:7825

* test/font-parse-testsuite.el (test-font-parse-data): New file.

shr.el: Revert change that made headings use different-sized faces.  The Emacs display engine isn't advanced enough that, for instance, tables can comfortably use differntly-sized faces.

mm-view.el (mm-display-shell-script-inline): Fix typo in docstring.
 (mm-display-javascript-inline): New function.
mm-decode.el (mm-inline-media-tests): Add application/javascript viewing function.
nnimap.el (nnimap-open-connection-1): Store the actual stream type used.
 (nnimap-login): Prefer plain LOGIN if it's enabled (since it requires fewer round trips than CRAM-MD5, and it's less likely to be buggy), and we're using an encrypted connection.
proto-stream.el: Alter the interface functions to also return the actual stream type used: network or tls.

* lisp/emacs-lisp/copyright.el (copyright-update-directory):
Undo part of previous change - don't find files literally, we need
comment-start-skip, etc.

literal "diff" (important for windows-nt).
