Automatically support arguments and command names with dashed variants? #49
Description
In most command-line interfaces, dashes are used in place of underscores, for both arguments and subcommand names. (git cherry-pick, svn co --ignore-externals, etc.)
This can be done in mando, but it requires extra steps. Dashed arguments can be achieved through adding a documentation string such as :param --ignore-externals: for the above example, and commands can be augmented with something such as @command("cherry-pick") for the above example.
It would be nice to have some method of achieving this automatically.
(p.s. mando is awesome!)
