Yes, the behaviour of the "exec" command changed sometime during the
development of the 2.0.xx series of fvwm2.  It used to always run a
"sh -c" before your command, but now it does the more efficient
straight exec of the first argument.  If you want the old semantics,
you need to explicitly go "sh -c".
