Git pager woes

Git doesn't set special options to it's pager command if the LESS
environment variable is set. I noticed when I started using Gentoo
that git was putting all output into a pager even if it were less than
one page, which it didn't do under Ubuntu. A fellow Gentoo user
confirms this; apparently Gentoo's defaults set LESS, but without a
-F.

Should git always tack on a -F when it invokes less, or should this be
put on the user to look up what to do? Or should I go complain to the
Gentoo folks?
