This doesn't change the automatic command finder, so it really only helps
increase match hit rate in case of low confidence level delta between the 2 top
hits. For example, given commands 'set-commit' and 'dcommit', a user typing
'set_commit' would hit:
- 'set-commit': 90%
- 'dcommit': 70.5%

Since subcommand.py uses a 30% minimum confidence level between the two top hit
to automatically select a command, it will err on the side of safety and will
abort instead of selecting 'set-commit'.

This change fixes this specific case but won't trigger on partial matches, e.g.
'set_commi' for 'set-commit'.

This officially drops support for '_' in command names, which is ugly as hell.
'_' was very rarely used so it shouldn't affect too much users.

Refactor the code to be more readable.

Because everyone needs humour.

Fix a small bug in subcommands.py with undocumented commands.

This makes it easier to type without using the shift-key, so an user can type
'git cl set-commit' and it'll find CMDset_commit.

Update subcommand to support examples, always disable format_description and
format_epilog and add colors when enabled.

Use the code in git_cl.py, since it was the more evolved. Add documentation
and clean up the structure along the way.

This makes it possible to easily reuse the generic subcommand handling code.

As a first step, only git_cl.py is using it. Eventually, gclient and gcl could
be switch over.
