Hmm, not sure I like it this way too much. Somehow I would have assumed
that this works like it does on the shell, i.e. you can name as many
globs as you wish, and they would be treated the same way. 

Now, if we want to expose what your patch currently does I'd prefer if
we did this via cmdline switches. i.e. "--pattern=*.target",
"--from-pattern=*.service", or "--to-pattern=*.waldo",

Also, if this is parsed out of the command line it's fine to place this
in global vars whose name is prefixed with "arg_" or so...
