The lack of this has annoyed me about mercurial for some time and this
message provoked me into looking again at how to make it work. So for
the benefit of others:

"hg diff -p" seems to work (this option didn't exist last time I looked,
which I admit was years ago) and adding 
        [diff]
        showfunc = True
to ~/.hgrc also works and seems to extend to "hg email" and "hg
tip" (which do not take a -p) as well so is probably sufficient for most
usecases.

Hurrah.

Ian.
