Code review comment for lp:~robertcarr/mir/multiwin-egl-example

You've broken specifying -m (the getopt string should be "hm:w:", because both m and w have a mandatory argument).

Also, this doesn't actually trigger the bug for me; if you're seeing problems, they're not the same as the nested-multi-output hang. That doesn't make this change unuseful, though. Fix the getopt string and you've got an approved from me.
