Unfortunately, no. If I make a patch without emacs, my editor will
still use something else than a mix of tabs and spaces, so it will
have to be OTP-ified by hand (copying indentation from other lines) or
by running it through emacs just for that.

Which, in a funny turn of events, brings me to a question related to
the previous "holy war": can emacs open, reindent and save files in
bach mode? That would indeed help! (even if one would still have to
install emacs).
