I see your point.  I was thinking more in terms of usable apis, it's
actually really hard for a hook to programmatically detect the "magic"
line and remove it, once it is mixed in with the rest of comment.  I'm
not sure how one would actually do this (especially keeping in mind
that we may change the phrasing, the string may occur in translated
form, etc.).

I think the bottom line is that it doesn't actually matter that much,
the commit message hook stuff is a bit of a mess anyway, there are
already things like the C++ generates the message about lines with
"MTN:" in front being removed, but it's the hook that actually defines
the MTN: prefixing/removal mechanism, etc... so basically, I would
just go with whatever is easiest.
