Subject: Provide help clicks on recently-used-engines menu items
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=c538ad128cef9fea034c4c67405cfb51dc2b6ce3;p=xboard.git

Provide help clicks on recently-used-engines menu items

The items for recently used engines in the Engine menu are now recognized
as such, and will look for help on "Recently Used Engines" rather than
on the item text (which is the engine name).
