I know about that but didn't really consider it a bug.  Yes, it would be
a little nicer if the illegal move check came first, but it's somewhat
messy since we don't really know what the move is (not completely)
until you say what you want to promote to.  In particular, in some
cases the chess engine is responsible for the legality checking.
Normally xboard just sends the engine your move and handles any errors
the engine may send back, but in this case, since we don't really know
the move for sure (you might even hit "cancel" on the promotion
dialog!), we'd have to put the engine in force mode, send it a promotion
to queen (say), then back that out and change it if you do something
else, then put the engine back into play-white or play-black mode.  I'm
not even sure that covers all the issues that would arise, such as
whether it unfairly takes pondering time away from the engine...
