I'm not sure why the diffs are showing up in that fashion - perhaps whatever
SVN-to-Git mapper is being used is screwing up - but if you ask SVN what
changes were done by

    r39082 | wmeier | 2011-09-21 11:55:03 -0700 (Wed, 21 Sep 2011) | 5 lines

    Whitespace cleanup:
     Use consistent indentation;
     Convert "4 space tabs" to spaces;
     Remove trailing whitespace.

and use "diff -w" so that whitespace changes aren't shown, you just get

so that change really *did* just tweak whitespace and change some modelines to
match - it didn't do anything with the menus themselves.  (As the official
Wireshark source repository uses SVN, SVN is the authoritative source here.)

menus.c disappeared in rev 39137:

    r39137 | jmayer | 2011-09-25 14:19:45 -0700 (Sun, 25 Sep 2011) | 4 lines

    We now always build with MAIN_MENU_USE_UIMANAGER, so remove all code using
    the old ways except the proto_help.c file, which is kept for now in case
someone
    is willing to reimplement the help menus using non-deprecated methods.   

An "svn blame" of ui/gtk/main_menubar.c doesn't seem to show any lines where
there was any accelerator for "Expand All", so perhaps it disappeared with the
changes to use GtkUIManager.  Unfortunately, with the disappearance of
ui/gtk/menus.c from the source, it doesn't appear to be easy to run "svn blame"
on it to see when it disappeared.

*However*, as a comment in main_menubar.c says:


/*
 * Main menu.
 * 
 * Please do not use keystrokes that are used as "universal" shortcuts in
 * various desktop environments:
 * 
 *   Windows:
 *  http://support.microsoft.com/kb/126449
 *
 *   GNOME:
 *  http://library.gnome.org/users/user-guide/nightly/keyboard-skills.html.en
 *
 *   KDE:
 * 
http://developer.kde.org/documentation/standards/kde/style/keys/shortcuts.h$
 *
 * In particular, do not use the following <control> sequences for anything
 * other than their standard purposes:
 *
 *  <control>O  File->Open 
 *  <control>S  File->Save
 *  <control>P  File->Print
 *  <control>W  File->Close
 *  <control>Q  File->Quit
 *  <control>Z  Edit->Undo (which we don't currently have)
 *  <control>X  Edit->Cut (which we don't currently have)
 *  <control>C  Edit->Copy (which we don't currently have)
 *  <control>V  Edit->Paste (which we don't currently have)
 *  <control>A  Edit->Select All (which we don't currently have)
 *
 * Note that some if not all of the Edit keys above already perform those
 * functions in text boxes, such as the Filter box.  Do no, under any
 * circumstances, make a change that keeps them from doing so.
 */

so, whilst having *some* accelerators for "Expand Subtrees" and "Collapse All"
would be useful, control-A as an accelerator could get in the way of, for
example, selecting all the packets and then copying to the clipboard as, for
example, a list of the packet summary lines, which might be a useful operation.
 Control-X for "Expand Subtrees" might be less of a problem, but it's still
probably best not to poach it.
