Subject: Fix Xaw key bindings
X-Git-Url: http://winboard.nl/cgi-bin?p=xboard.git;a=commitdiff_plain;h=ead2d5b5a7747a578e20f88442473b43a66ccc86

Fix Xaw key bindings

The routine to automatically construct the translation table for
accelerator keys did not respect the rule that more specific keystrokes
(like :Meta<Key>Home:) have to be defined before more general ones
(like :<Key>Home:). As a result Alt+Home would activate the Revert
item, intended for plain Home.
