* lisp/international/fontset.el (setup-default-fontset): Revert
the change "Configure Symbola font only if installed", since font
search is evidently not yet set up when this function is called.
(Bug#20727)

* lisp/emacs-lisp/warnings.el (display-warning):
If startup isn't complete, delay the warning.

* lisp/startup.el (normal-top-level, command-line):
Let display-warning automatically handle the needed delays.
Run delayed-warnings-hook.

Avoid calling external executable if possible.  (Bug#20799)

* lisp/help.el (help-split-fundoc, help--make-usage-docstring):
Document (backquote FOO) as "`FOO", not as "(` FOO)" (Bug#20759).

* lisp/international/fontset.el (setup-default-fontset):
Don't specify the Symbola font if it's not installed.
Likewise for FreeMono.  (Bug#20727)

* lisp/international/fontset.el (setup-default-fontset): Leave
only symbols and punctuation in the fontset setup for Symbola
font; remove "Greek and Coptic" and "Cyrillic Supplement".
(Bug#20798)

* src/fontset.c (Ffontset_info): Check that the RFONT-DEF elt is
non-nil.

* configure.ac (SETUP_SLAVE_PTY) [sol2* | unixware]:
Adjust to process.c change.
* src/process.c (create_process): Declare volatile variables at
top level of this function, so that they're less likely to be
reused later in the function in the code executed by the vforked
child.  Do not declare locals used only in the vforked child, as
they might share memory with locals still live in the parent.
Instead, use the same variables in the child as in the parent.
This works around a subtle bug that causes a garbage collector
crash when Emacs is built with Sun C 5.13 sparc on Solaris 10.

a nil default-directory.

* src/buffer.c (init_buffer): Handle get_current_dir_name failures.

* lisp/startup.el (normal-top-level, command-line-1):
* lisp/minibuffer.el (read-file-name-default):
Handle default-directory being nil.

* configure.ac (PTY_OPEN): Define to plain 'open'
on SVR4-derived hosts, so that the O_CLOEXEC flag isn't set.
* src/process.c (allocate_pty): Set the O_CLOEXEC flag after
calling PTY_TTY_NAME_SPRINTF, for the benefit of SVR4-derived
hosts that call grantpt which does its work via a setuid subcommand
(Bug#19191, Bug#19927, Bug#20555, Bug#20686).
Also, set O_CLOEXEC even if PTY_OPEN is not defined, since it
seems relevant in that case too.

* lisp/simple.el (kill-region): Replace 'error' with 'user-error'.
(Bug#20785)

While investigating Bug#20759, I discovered other quoting problems:
C-h f mishandled characters like backslash and quote in function names.
This fix changes the behavior so that 'C-h f pcase RET' now
generates "... (\` QPAT) ..." instead of "... (` QPAT) ...",
because '(format "%S" '(` FOO))' returns "(\\` FOO)".  A comment
in src/lread.c's read1 function says that the backslash will be
needed starting in Emacs 25, which implies that 'format' is
correct and the old pcase documention was wrong to omit the backslash.

* lisp/help-fns.el (help-fns--signature):
* lisp/help.el (help-add-fundoc-usage):
* lisp/progmodes/elisp-mode.el (elisp-function-argstring):
Use help--make-usage-docstring rather than formatting
help-make-usage.
* lisp/emacs-lisp/pcase.el (pcase--make-docstring):
Return raw docstring.
* lisp/help-fns.el (help-fns--signature): New arg RAW, to return

command keys.
* lisp/help.el (help--docstring-quote): New function.
(help-split-fundoc): Use it, to quote funny characters more
systematically.

should be private.  Leave an obsolete alias for the old name.
(help--make-usage-docstring): New function.
* test/automated/help-fns.el (help-fns-test-funny-names): New test.

since in-string-p is not used in thingatpt.el but only from outside.

Also, use lexical binding.

* test/automated/let-alist.el (let-alist-cons): Test it.
