[TxMt] Commit update (was Re: Escape eats my checkin!)

[Chris Thomas]

I just checked in a new version of CommitWindow with two user-visible  
modifications:

• Deselect external items by default.
• Preserve the last few commit summaries in a persistent pop-up menu.  
Summaries are saved even when the commit is canceled.

To get it, you'll need to check out the latest version of  
$TM_SUPPORT_PATH/CommitWindow.app. You don't need to update  
Subversion or the other version control bundles.

As for word completion with escape, one could remove the escape key  
equivalent from the cancel button, but keyboard-only users still need  
a way to cancel.
