handle_command: Skip commands that has a criteria string.

Browse source 
We can't handle them currently (the criteria needs to e.g. be passed to
each command handler which then needs to do the right thing), so it's
better to just do nothing than to create unexpected results (because the
command was executed on the wrong view).

(Before this patch any command list with a criteria string would simply
fail to parse, so this is at least a step in the right direction.)
