Maintainer's notes:

• This is blocked on pulling out the parser ([modular] Pull out a clap_lex #2915) so we can then abstract it and allow alternative syntaxes

Hi, I would like to begin porting a piece of command line software to rust which uses arguments of the style "-argument" with a single hyphen instead of the usual "--argument" with two hyphens preceding the name of the argument, I would like to use clap for parsing these arguments, but it sounds like clap does not yet support this functionality?
