FWIW '.' is not equivalent to '' when it comes to grep or such commands,
you should suggest '^' or '$' instead, otherwise you'll miss empty lines
and users will continue to use '' for that purpose. BTW I do use grep ''
a lot, but only on file systems, not within git (eg: to display contents
of /sys).

Cheers,
