Automatically upgrade '_' to '-' when finding the right command.

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'.
