I was curious how hard it would be to find unused ones, and it is not too bad:

It turns up many hits, depending on what built cruft you have in your directory (having a crufty state is nice because it shows which patterns are used, but it also may mean you have leftover trash from old versions that doesn't get built anymore, and which we wouldn't notice). So I think a human has to apply some brain-power to the result to see which ones are plausibly created by other people's environments.

You might want to revisit some of the old dist rules (do we still ever build git-core-*? "make dist" doesn't seem to. Likewise, "make rpm" and "make deb" are no more, so perhaps it's time to drop those ignores.

The one below didn't take much brain-power, though.

Subject: [PATCH] gitignore: drop duplicate entry for git-sh-i18n

This was accidentally added by e00cf070a4 (git-sh-i18n.sh: add no-op gettext() and eval_gettext() wrappers, 2011-05-14), even though an earlier commit in the same series had already done so.
