bug#4339: 23.1.50; NextStep emacs port problem with key sequences in men

Subject: bug#4339: 23.1.50; NextStep emacs port problem with key sequences in menus (with patch)

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

In the ns/cocoa version of Emacs 23 when key sequences are added to menu
items via calls such as easy-menu-define, key sequences that start with
s end up showing up as just the Command key with a single letter. In
previous versions of emacs for the Mac (Carbon Emacs), the key sequence
would show up correctly.  For
packages such as YaSnippet this becomes a problem because the key
sequence that is shown is the snippet you must type to get an
expansion. For example, in snippets that I currently use typing
shbt <tab> expands to "should belong to". In previous versions of emacs
the menu item for this would show

should_belong_to ... (shbt =>)

In the next step version of emacs it shows

should_belong_to ...     ⌘B

The following patch makes does a bit more of a check in parseKeyEquiv in
nsmenu.m to fix the issue.

Subject: [PATCH] Changed nsmenu so that parseKeyEquiv can handle when menus are created with key combinations that start with s, but do are not supposed to be intermpreted as meta.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/Applications/Emacs.app/Contents/Resources/etc/DEBUG for instructions.
