* src/print.c: Include <c-ctype.h>, for c_isxdigit.
(print_object): When print-escape-multibyte is non-nil and a
multibyte character is followed by a newline or formfeed, followed
by a hex digit, don't output a needless "\ " before the hex digit.
* test/automated/print-tests.el (print-hex-backslash): New test.
* src/xdisp.c (syms_of_xdisp): Define a boolean `inhibit_message'.
(message3): Don't call `message3_nolog' (i.e. use the Echo Area) when
`inhibit_message' is non-zero.
* etc/NEWS: Add an entry.
* doc/lispref/display.texi: Add an entry for `inhibit-message',
mention it in `message'.
In case `(and (null custom-file) init-file-had-error)' do the same
thing we'd do if `(null user-init-file)', which is to either error out
or return nil. This is in line with `custom-save-all' which would
throw an error in that situation. (bug#20355)
(package-menu-hide-low-priority): New variable, see its doc.
(package-archive-priorities): Update doc.
(package-desc-priority): New function.
(package-desc-priority-version): Use it.
(package--remove-hidden): New function.
(package-menu--refresh): Use it.
(package-menu--hide-obsolete): New variable.
(package--remove-hidden): Use it.
(package-menu-hide-obsolete): New interactive function to toggle
the variable.
(package--quick-help-keys): Document it.
(package-menu-async): Add :version tag.
(package-menu-mode-map): Bind package-menu-hide-obsolete.
(package-desc-status): Indicate non-installed obsolete packages as
avail-obso.
(package-menu-mark-install): Allow installation of avail-obso.
(package-menu--status-predicate): Sort avail-obso with available.
* reftex-cite.el (reftex-extract-bib-entries): Fix
`wrong-type-argument stringp nil' error that occurs when AUCTeX
integration is enabled and there are no citations in the document
so far.
* lisp/vc/vc-git.el (vc-git-find-file-hook): Add
`vc-git-resolve-when-done' to `after-save-hook' in either case.
(vc-git-conflicted-files): Add a TODO.
(vc-git-resolve-when-done): Depending on the presence of
MERGE_HEAD, either update the resolved file in the index, or
remove it from there. (Bug#20292)
* lisp/files.el (save-buffer): Pass interactive flag to `basic-save-buffer`
(basic-save-buffer): Accept called-interactively as an argument instead of
directly invoking called-interactively-p, which will always yield nil
in that context.
Fixes bug#20266.
lisp/progmodes/cc-mode.el (c-basic-common-init): Make
yank-handled-properties buffer local, and remove 'category from it.
(c-called-from-text-property-change-p): New function.
(c-before-change): Don't do anything if a call of the new function
returns non-nil.
(c-after-change): Don't do much if a call of the new function returns
non-nil.
(c-extend-after-change-region): Put changes to text property 'fontified
inside c-save-buffer-state.
(package-menu-filter): Accept a list of keywords.
(package--all-keywords): New variable to cache known keywords.
(package-all-keywords): Populate it if necessary.
(package-refresh-contents): Reset it.
(package--has-keyword-p): Understand "arc:xxxx" and "status:xxxx"
as special keywords which match agains package archive and status
respectively.
* etc/NEWS: Document it.
* lisp/emacs-lisp/package.el (package--read-archive-file):
Set `coding-system-for-read' explicitly to 'utf-8 when reading the
downloaded and cached archive-contents files, so that non-ASCII
characters in package descriptions are displayed correctly in the
`list-packages' menu. (Bug#20231)

* src/print.c (PRINTDECLARE): Remove. Move its contents into
PRINTPREPARE; doable now that we assume C99. All callers changed.
(PRINTCHAR): Remove, as it adds more mystery than clarity.
All callers changed.
(strout): Assume that caller computes length. All callers changed.
(print_c_string): New function.
(write_string, write_string_1): Compute length instead of asking
the caller to compute it. All callers changed.
(write_string): Simplify by using write_string_1.
(write_string_1): Simplify by using print_c_string.
(Fterpri): Compute default val more clearly.
(Fprin1_to_string, print_object):
Assume C99 to avoid unnecessary nesting.
(print_object): Prefer print_c_string to multiple printchar, or
to calling strout with -1 length. Coalesce into sprintf when
this is easy.
