(rectangle-coerce-tab): No longer used; deleted.
* rect.el (open-rectangle): Leave point at the upper corner of the
rectangle just opened, in imitation of open-line. Fix doc typo.
(open-rectangle-line): Use skip-chars-backward's LIM argument to
leave spaces before the line segment's beginning undisturbed.

Added VMS changes from Roland Roberts.
* process.c (read_process_output): Save, widen, insert the process
output, and then restore the restriction if inserting text outside
the visible region.
* process.c (Fstart_process): Establish an unwind-protect to
remove PROC from the process list if an error occurs while
starting it.
(start_process_unwind): New function to help with that.
(create_process): There's no need to explicitly call
remove_process if the fork fails; the record_unwind_protect in
Fstart_process will take care of it.
* process.c (wait_reading_process_input): Test the C preprocessor
symbol "ultrix", not "__ultrix__" to see if we should ignore
ENOMEM errors from select.
* process.c (process_send_signal): On systems which have both
the TIOCGETC and TCGETA ioctls, just use the former.
* s/bsd4-2.h, s/bsd4-3.h: #define SIGNALS_VIA_CHARACTERS.
* process.c (process_send_signal): Put all the code for sending
signals via characters in a #ifdef SIGNALS_VIA_CHARACTERS. Decide
whether to use the Berkeley-style or SYSV-style ioctls by seeing
which ioctl commands are #defined.
* process.c (process_send_signal): Doc fix.
unread_command_char to unread_command_event.
* minibuf.c (read_minibuf): If get_minibuffer gives the
new minibuffer a nil default directory, find another buffer with a
better default directory and use that one's instead.
(Fread_char, Fread_char_exclusive): Don't signal an
error for or throw away switch-frame events; instead, put them off
until after we've found a character we can respond to.
Rename unread_command_char to unread_command_event; it has
subtly different semantics now, and we should use
`make-obsolete-variable' to warn people.
* lread.c (Fread_char): Change reference.
* keyboard.c (Vlast_event_frame): Doc fix.
* keyboard.c (read_char): Write composite events to the dribble
file properly.
* keyboard.c (init_keyboard): Initialize Vlast_event_frame to
Qnil, rather than the selected frame.
* keyboard.c (lispy_modifier_list): Added sanity check before
indexing into modifier_symbols.
* keyboard.c (add_command_key): When copying the contents of the
old this_command_keys to new_keys, remember to multiply size by
sizeof (Lisp_Object) to get the amount we really need to copy.
Rename unread_command_char to unread_command_event; it has
subtly different semantics now, and we should use
`make-obsolete-variable' to warn people.
* keyboard.c (unread_command_char): Rename.
(command_loop_1, read_char, Finput_pending, Fdiscard_input,
quit_throw_to_read_char, init_keyboard, syms_of_keyboard): Change
references.
* keyboard.c (read_key_sequence): Don't use
save_excursion_{save,restore} to protect the caller against buffer
switches; use Fset_buffer and Fcurrent_buffer; redisplay might
change point, and we don't want to undo that.
* keyboard.c (kbd_buffer_get_event): When checking a mouse
movement for a frame switch, don't assume Vlast_event_frame
contains a Lisp_Frame object.
number of arguments to mark_window_display_accurate.
* dispnew.c (safe_bcopy): Use the right terminating condition in
the loop which uses multiple bcopy calls to transfer a block to an
overlapping higher block.
* buffer.c (Fbury_buffer): Make this behave as in 18.59, although
that behavior is very odd - only remove the buffer from the
selected window if BUFFER was nil or omitted.
* process.c (process_send_signal): Put all the code for sending
signals via characters in a #ifdef SIGNALS_VIA_CHARACTERS. Decide
whether to use the Berkeley-style or SYSV-style ioctls by seeing
which ioctl commands are #defined.
* make-dist: Don't forget that the way to avoid filenames starting
with `=' is to use the pattern `[a-zA-Z0-9]*.h', not
`[a-zA-Z0-9].h'. Add a new section for dealing with files that we
couldn't make hard links to, since we have two already, and
perhaps more to come.
