Bug#743716: xboard: analysis mode is broken when xboard is upgraded from 4.6.2-1 to 4.7.3-1

[Kamaraju Kusumanchi]

Package: xboard
Version: 4.7.3-1
Severity: normal

Dear Maintainer,

In the old version 4.6.2-1, when I do

rajulocal at hogwarts:~/chess$ xboard -fcp crafty
KamarajuKusumanchi_vs_paconov_2014_04_02.pgn

the game will start playing automatically. It can be stopped and moved to the
beginning of the game by clicking on the "<<" button at the top right. Now if I
press ctrl-A, the analyis mode will start and the analyzed moves will appear in
a separate window. The analysis mode can also by started by Mode -> Analysis
Mode. Once the Analysis Mode starts, I can step through the program by pressing
">" button at the top right.

In the new version 4.7.3-1, this behaviour is broken. After loading the game,
clicking on the "<<" button, if I press ctrl-A, nothing happens. The Analysis
Mode under Mode menu is greyed out and not clickable. In both the cases above,
I have crafty 23.4-6 installed.

rajulocal at hogwarts:~/chess$ dpkg -l crafty
