Yes, 79 or 80.

Or you could insert the reencoding magic after (and separately from) the
dos2unix magic, if that would make counting easier. That said, what are
you trying to count? The number of properties where the reencoding
wasn't a noop?
Re performance, isn't svnsync bound by network speed?
Unrelatedly, you mentioned that in the repository you work on there are
soem properties in latin1 and some in utf8. So one will need (until
they fix the properties on their side) to svnsync a few revisions with
translation enabled, then kill svnsync and restart with translation
disabled, then restart again with it enabled etc. Which makes me think,
do we want a "sync up to N revisions" (or, "sync up to rN") switch?

Have you sent a new version of the patch yet?
