Support options of the form "-<number>" (hyphen immediately followed by a number)

[amynbe]

Like the max-count option in git log:

-<number>
-n <number>
--max-count=<number>

Or the -n option in gnu head/tail

Also it would be nice if the library had appropriate visibility of utility methods so a user can implement such behaviour himself (I don't think that's the case currently, e.g internal object PosixNaming).
