instead of
just being in the correct directory and giving interestingproject.

Path starting in "\\?\" (if I remember the syntax correctly) get parsed by
another parser and can be something like 32 kB in length. Somewhere (I think it
is in APR), absolute paths get this string prepended, but it can't do that
for performance reasons. I think you should try some svn commands
with relative and absolute paths and see if this makes a difference.

I think it is clear that this is a known "defect" in svn/apr (or at least
an understood tradeoff), the rest of this discussion could move to users@.
