Hi,

The usual way to resolve this problem is to require that optional option
arguments follow their option letter directly:

-ffilename  or --file=filename   ## option with argument
-f -g       or --file -g         ## two options without argument
-f filename or --file filename   ## one option and one unrelated
                                 ##    non-option argument

So, no ambiguity there: whether the argument's named "filename" or "-foobar"
doesn't matter (except in the third example, of course, but that's hardly
news).
