Yeah, /path/to/repos was meant to represent a URL path. I don't know
much about diff programs on Windows... does TortoiseSVN provide a way to
do a diff between arbitrary URLs?

It works for me. If it had been just -rN, then it would have failed
with a "path not found" error (but will work in 1.1, I believe).
However, -rN:HEAD works because /tags/1.0.2/foo.c does exist in the HEAD
revision, and Subversion can just follow the log messages back from
