topgit has an issue with that: https://github.com/greenrd/topgit/blob/master/tg.sh#L462
TG_PAGER gets defined some lines above ${FOO-xxx) means but word if FOO
isn't defined (thanks to Lethalman, I failed finding that in the man
page.
Is the best way to fix this by dropping quotes? Does anybody know how
PAGER ist most commonly used?
