Hello!

I have the same issue as John Cheetham, from his post a couple of
years ago.  The issue persists with the latest build I could find,
6.2.5e.  I use both Scid and Xboard and, in both cases, they appear to
hang when trying to play a game against gnuchessu.  When running
gnuchessu from the command line, the appearance of 'White (1) : "
requires at least a newline to be entered before the 'uci' command
will work as expected.

It seems related to the removal of the 'showprompt' and 'ShowPrompt()'
lines from main.cc and frontend/engine.cc from 6.2.4 but I do not know
enough about C programming to fix it - other things break if i just
add the deleted lines back in.

Ryan
