* lisp/eshell/esh-mode.el: (eshell/clear): Use (window-size) as the
number of newlines to be inserted. This fixes the issue where
eshell/clear wouldn't work if the prompt was not at the bottom of the
window, and the output wasn't too long.

; * etc/NEWS: Document `search-default-regexp-mode'

* lisp/character-fold.el: Make compatible with lax-whitespace

(character-fold-to-regexp): Rework internals to play nice with
lax-whitespacing.

When the user types a space, we want to match the table entry for
?\s, which is generally a regexp like "[ ...]".  However, the
`search-spaces-regexp' variable doesn't "see" spaces inside these
regexp constructs, so we need to use "\\( \\|[ ...]\\)" instead (to
manually expose a space).

Furthermore, the lax search engine acts on a bunch of spaces, not
on individual spaces, so if the string contains sequential spaces
like "  ", we need to keep them grouped together like this:
"\\(  \\|[ ...][ ...]\\)".

* lisp/isearch.el: Refactor momentary messages

(isearch--momentary-message): New function.
(isearch-toggle-lax-whitespace, isearch-toggle-case-fold)

(isearch-toggle-case-fold, isearch-toggle-invisible)
(isearch-toggle-regexp, isearch-toggle-lax-whitespace): Define
with `isearch-define-mode-toggle'.

Avoid using `add-to-list' on a let-local var in tramp-smb.el

* lisp/net/tramp-compat.el (tramp-compat-delete-dups): New defun.
* lisp/net/tramp-smb.el (tramp-smb-handle-directory-files): Use it.

* lisp/net/tramp-smb.el (tramp-smb-handle-directory-files):
Revert 692bce5b9eccfae19ae2a5a23a9ccd8d6bf86076, `delete-dups'
does not exist in XEmacs 21.4.

Fixed OS X startup crash.

Input events started to arrive before ns_term_init() was finished.
Solved by blocking input. This also seems to correct the "You
can't open the application "Emacs" because it may be damaged or
incomplete" error issued when double-clicking on the Emacs
application.

* nsterm.m (ns_constrain_all_frames, ns_init_term): Block input.
* nsterm.m (ns_send_appdefined, EmacsApp): Trace output.

* src/process.c (Fget_buffer_process): Improve docstring

Document the fact that it doesn't return dead processes.
