It's probably better to get in the habit of using :redo than the period
to undo an undo, since :redo (or :red for not-very-short) can advance
through several levels of undos, but the period can only repeat one
single thing over and over again.  If you're six levels back in undos,
and you want to undo all six levels, but you use the period once, I think
that'd wipe out all those levels of undo so they aren't recoverable.

I haven't directly tested that recently, but that's how I recall it
working back when I first learned about multiple undo/redo levels for
Vim, lo these many moons ago when the world was young and dinosaurs
roamed the Earth.
