Re: Serious bug with pretty format strings & empty bodies?

Hi,

I ended up trying to filter-branch my repository, see if I could come
up with a version stripped of all our private code, suitable for
making public.  Disappointingly, filter-branch magically fixes all the
commits, even when simply run as "git filter-branch HEAD".

However, looking at the rewritten repository vs the original, they
share a lot of commits, then diverge halfway through their history.  I
can't see anything notable about the commit where they diverge, with
the exception that the rewritten commit has a newline after the
subject and the original doesn't.  Neither has a commit message body.

I do not see how Rene's patch could _not_ have fixed that problem.

As it is, I cannot even reproduce without that patch.  This is what I was 
trying:

-- snip --

diff --git a/t/t4025-pretty-format.sh b/t/t4025-pretty-format.sh
new file mode 100644

Seems I cannot help any more, but at least this is a starting point to 
try to reproduce.

Ciao,
