Fixes the bug

This fixes the bug, the overflow doesn't happen anymore, I've tried up to ~4093
long command-lines(couldn't go beyond that because of some console/cmd/input
limitation in wine), may be with a batch file I could go up to 8192.

I think that some tests should be added to make sure that long-command lines
work with cmd
