In case it matters, that patch was generated with simple "git diff"
and then hand edited to prepend the commit log, S-o-B, and comments.
I'm still too chicken to use git-mail.
I haven't touched that tree since making the diff. Any information
that might help explain the state is available. Here are some basics:

Just for grins, can you apply the patch by hand?
patch -p1 < grundler.eml
This would just confirm it's not a problem with the "diff" portion of
the patch. It's possible something else in the file is
confusing/annoying git-am command.
