Subject: Fix sub-variation display with negative score
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=77a5189fa223ed2a484e1715ad760a8396a7ad7e;p=xboard.git

Fix sub-variation display with negative score

The test if the displayed score was the pvInfo score failed for negative
scores, because floats are truncated towards zero. So the previous fix
of spurious score/depth info was not working when the score was
negative.
