Subject: Keep list of excluded moves in Engine Output header
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=c082824a507c0fb577beb908ed5615a161c6c6fa;p=xboard.git

Keep list of excluded moves in Engine Output header

As long as there is still space, excluded or included moves are added
to a new header line in the Engine Output window (prefixed with + or -
depending on whether they are currently excluded or included). Future
in/exclusions of that same move then alter the prefix.
