Re: git am fails because of weird text in commit log

Quite understandable.

Shouldn't git format-patch at least complain about commit log
like this, if not mangle it in some way?

It probably is too early to warn, mangle or quote in "git commit".
I agree with you that "git format-patch" would be the best step in a
typical workflow to warn, mangle or quote.

The solution would probably begin with identifying the lines in the
commit log that mailinfo.c::patchbreak() considers the beginning of
the patch part.  After finding such a line:

 - Warning is easy.  

 - Mangling the line by prefixing something like " " in front of it
   would also be easy.

 - Quoting thru to the end of "patch that shouldn't have been there"
   in possibly a reversible way is probably too hard.

Mangling or quoting should be hidden behind an option, I would
think.

Patches welcome.

Thanks.
