Subject: Fix Bridges keyboard cursor vertical out-of-bounds error.
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?p=sgt-puzzles.git;a=commitdiff_plain;h=75335f199ea5fbc7b1af890473ec98dc340c2ae8

Fix Bridges keyboard cursor vertical out-of-bounds error.

Position the cursor in the top (bottom) row, press enter and press up
(down).  The game acts as if you had pressed right, both with Enter-
and Space-based dragging.
