Not much, considering how often I consult these manpages.

Our git-manpages package doesn't build the manpages from source anyways.
It simply unpacks a tarball of pre-built manpages.

I agree. If we continue to not build them from source, it won't make the
Git package any more "expensive". We could add the pre-built source
tarball as a native-input to the Git package, and re-use the unpack
phase from git-manpages.

I think the current arrangement offers a bad experience for new users
who can't find the manpages.
