Subject: Reset protocol version before loading new engine
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=3ba96d80b42bb16b32f9ba305028840bacdb9cc7;p=xboard.git

Reset protocol version before loading new engine

The protocol version was not reset, so if the previous engine was v1,
the newly loaded engine would not be sent a protover command, so
that its features would remain unknown!
