You shouldn't modify the "command" parameter. This one ought to be
constant, even if it's not currently marked so.
It's better to change the "string" string.

Also you should add testcases to cmd's test suite, possibly as a
preliminary patch of a series, but it can also be together with the
patch. That's up to you.

Also for single patches, you don't need "[1/1]"... use git
format-patch "-k" option, or edit the subject before submission.
