This fixes bug #33602 and is a partial reversion of a commit from
2018-11-28T13:15:50.
* lisp/emacs-lisp/bytecomp.el (byte-compile-log-file): Don't create buffer
*Compile-Log* because it doesn't already exist. Amend message "Compiling no
file" to be clearer (?and less irritating).
* lisp/eshell/em-dirs.el (eshell-write-last-dir-ring):
* lisp/eshell/em-hist.el (eshell-write-history): Don't call
file-truename with argument of nil. (Bug#33477)
* test/lisp/eshell/eshell-tests.el (with-temp-eshell): Remove
HISTFILE from the environment, to make sure the Eshell history
file is nil.
* src/alloc.c (VECTOR_ELTS_MAX): New constant.
(allocate_vectorlike): LEN now must be positive. Assume LEN
is in range. All callers changed.
(allocate_vector): Arg is now ptrdiff_t, not EMACS_INT.
All callers changed. Return zero vector here, not in
allocate_vectorlike.
* src/lisp.h (make_uninit_vector): Simplify.
* src/xwidget.c (webkit_js_to_lisp):
Check for overflow in ptrdiff_t calculations.
Revert replacing a backquote in the "copyright" skeleton with a quote
done in "Replace insignificant backquotes" which broke the skeleton.
* lisp/emacs-lisp/copyright.el (copyright): Restore the correct
version of the skeleton that used a backquote.
* lisp/dired.el (dired-save-positions, dired-restore-positions):
For each window that showed the reverted buffer before, fix the
point positions in its list of previously shown buffers the way
these routines handle window point for all windows currently
showing the buffer (Bug#33458).
* lisp/window.el (balance-windows-2): When a child window has
fixed size, don't count it as resizable (Bug#33254).
Handle case where a window has no resizable child windows.
This fixes bug #32808.
* lisp/progmodes/cc-engine.el (c-beginning-of-statement-1): New variable
comma-delimited, set when we're about to scan backward over a comma. Do not
reckon a brace block as bounding a statement when it is followed or preceded
by a comma (except when argument comma-delim is non-nil).
(c-guess-basic-syntax, CASE 9C): Call c-beginning-of-statement-1 with argument
comma-delim changed to non-nil.
* src/w32.c (w32_get_current_directory): New function.
(GetCachedVolumeInformation, init_environment): Use it.
(w32_init_current_directory): New function.
* src/w32.h (w32_init_current_directory): Add prototype.
* src/emacs.c (main) [WINDOWSNT]: Use w32_init_current_directory
to get the accurate value of cwd. This is needed to record
the correct directory in emacs_wd, which is now initialized
way earlier in the startup process, when init_environment was
not yet called. For details, see the problems reported in
http://lists.gnu.org/archive/html/emacs-devel/2018-12/msg00068.html.

* lib-src/emacsclient.c (process_grouping): New function.
(act_on_signals, main): Use it.
(main): Omit "Waiting for Emacs..." and later "\n" messages
if in background, since that messes up the screen.
Problem reported by Kaushal Modi in:
https://lists.gnu.org/r/emacs-devel/2018-12/msg00083.html
The tcdrain call replaced an fdatasync call which had no
effect on the tty, so removing it entirely shouldn’t cause
problems. The fdatasync call replaced an fsync call which
also had no effect on the tty, and the fsync call seems to be
badly-merged revenant of emacsclient’s old (circa 2004) way of
communicating to and from Emacs via FILE * streams, where
fsync was apparently needed when talking to sockets.
* lib-src/emacsclient.c [!DOS_NT]: Don’t include termios.h.
(flush_stdout): Remove. All callers removed.
(main): Do not drain the tty after "Waiting for Emacs..."
message. There should be no need to drain, and draining it
might send us a SIGTTOU. Do not fflush stdout just before
exiting, as exiting does that for us.
* lisp/net/tramp-rclone.el (tramp-adb): Require.
(tramp-rclone-file-name-handler-alist):
Use `tramp-adb-handle-expand-file-name'.
(tramp-rclone-flush-directory-cache): New defun, derived from
`tramp-rclone-flush-mount'.
(tramp-rclone-do-copy-or-rename-file)
(tramp-rclone-handle-delete-directory)
(tramp-rclone-handle-delete-file)
(tramp-rclone-handle-make-directory): Use it.
(tramp-rclone-handle-directory-files)
(tramp-rclone-local-file-name):
Use `tramp-compat-file-name-quoted-p', `tramp-compat-file-name-quote'
and ´tramp-compat-file-name-unquote'.
(tramp-rclone-handle-file-executable-p)
(tramp-rclone-handle-file-readable-p): Cache result.
(tramp-rclone-handle-file-name-all-completions)
(tramp-rclone-mounted-p, tramp-rclone-remote-file-name)
(tramp-rclone-maybe-open-connection): Rewrite.
* test/lisp/net/tramp-tests.el (tramp--test-rclone-p): New defun.
(tramp-test05-expand-file-name-relative)
(tramp--test-special-characters): Use it.
* lisp/net/tramp.el (tramp-dissect-file-name, tramp-dissect-hop-name):
Check, that method is capable of multi hops.
* test/lisp/net/tramp-tests.el (tramp-test02-file-name-dissect)
(tramp-test02-file-name-dissect-simplified)
(tramp-test02-file-name-dissect-separate): Suppress check for multihops.
(tramp-test03-file-name-method-rules): Check for error if multi
hops cannot be applied.
* lisp/international/mule-conf.el (ibm038): New charset.
(ebcdic-int, cp038): Alias charsets of ibm038.
* lisp/language/english.el (ibm038): New coding-system.
(ebcdic-int, cp038): Alias coding-systems of ibm038.
(Bug#33612)
* etc/NEWS: Announce the new coding system ibm038.
with shift-move related options extracted from `search-exit-option'.
(isearch-pre-command-hook): Rename search-exit-option to
isearch-yank-on-move in shift-move related places.
(isearch-post-command-hook): Check for isearch-pre-move-point
instead of search-exit-option. (Bug#15839)
* doc/emacs/search.texi (Not Exiting Isearch): Rename
search-exit-option to isearch-yank-on-move.
* lisp/menu-bar.el (menu-bar-i-search-menu): Add more isearch commands.
(isearch-pre-command-hook): Call isearch-pre-scroll-point unless
isearch-allow-scroll is 'unlimited'.
(isearch-post-command-hook): Use `when' instead of `cond'.
Call isearch-lazy-highlight-new-loop when isearch-allow-scroll is
'unlimited'. (Bug#15839)
