Bug#725083: xboard: sends "level" command only to 1 engine

[folkert]

Package: xboard
Version: 4.7.2-1
Severity: normal

invoking:
xboard -firstChessProgram ./dn.sh -secondChessProgram ./do.sh

Then starting an engine match between these two with fixed time; each get 5 seconds per move.
Xboard then only sends to the "first chess program" the "level 40 5 0" command. This gives a mismatch.
