Sure. And if a tool ends up eating the changelog as a diff, then that tool 
is broken. I really do think that this is a "patch" bug - I really don't 
think that that was a valid traditional diff with the four spaces at the 
head of the line.

Of course, if the changelog-followed-by-diff doesn't have any indentation 
or escaping at all, the changelog entry itself *could* actually have a 
real unified diff in it, and the tool would be unable to tell where the 
actual patch starts.

But at least "git show" and friends indent the changelog on purpose, 
exactly so that there is never any chance that there could be any real 
ambiguity, and this really was a "patch" bug as far as I can tell. 
Happily, one that is easy to work around, by just telling patch to always 
consider the patch a unified diff.
