Cap command size passed to subshell

[Leonard den Ottolander <leonard den ottolander nl>]

Hi,

A small fix for the size of the command passed to the subshell pty. 4096
bytes should be enough, right? I believe the compiler should optimize
the double call to strlen(command) away. If not we could introduce an
extra variable here and set it first.

Leonard.
