 Hi,

 Unfortunately mailer.py doesn't use svnlook at all and I don't know
anything about svn bindings for Python (I'd like to learn about them but
this will have to wait...) so the patch would need to be done very
differently for it. And then there is a fact that I have quite a few post
commit hooks in my own repositories using commit-email.pl and deprecated
though it is, I have absolutely no complaints about it.

GS> Also note: you didn't attach the actual patch :-P

 Actually I did, as a text/plain attachment with inline disposition but it
somehow seems to have been lost on its way... Really no idea what happened,
sorry. But here is the patch again, this time inline.

 Thanks again,
VZ
