It's generally possible to do this with a multi-line string.  You can
write something like this:

$ git commit -m 'git: make boring change

Add this boring change so that people are put to sleep.  They will be
able to sleep well and therefore awake refreshed.
'

Your shell will usually indicate some sort of continuation prompt due to
the multi-line string, and you can simply close the single quote when
you're done.  This also works in shell scripts, and our testsuite uses
this syntax extensively.

If you need to insert a single quote, you can do this:

$ git commit -m 'git: make boring change

Add this boring change so that people are put to sleep.  They'\''ll be
able to sleep well and therefore awake refreshed.
'

Of course, the benefit to using an editor is that you can edit your
changes, so you may find that while this works, dealing with the
occasional typing mistake is inconvenient.
