Subject: Fix AppendComment
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=9e48fa42bfc24291f84c50545488893df964b0d8;p=xboard.git

Fix AppendComment

The joining of two comments was not performed correctly if the second
one had the braces yet to be added: the closing brace was not added in
that case.
