[PATCH] maint: spelling fixes

[Paul Eggert]

I ran my little spell-checking program and pushed the following
as (I hope) obvious.  I took the liberty of replacing "facultative"
with "optional", since I hadn't a clue what "facultative" meant
until I looked it up and it does seem to be a term that's used
in biology rather than in computing.
