Yep. APR is doing the right thing throughout, as far as my previous
research could show.

I think a guy that shows up with a patch is at least twice as loud as
those who don't (myself included). :-) I'm not fond of adding more
OS-specific code to Subversion, but if you can find a way to
minimalize the reaches of that, it could be worth it.

Also, (b) is likely the less hurtful solution. On Windows systems <
Win2k, switching to absolute paths all over would probably just
exacerbate the problem of long paths, since those system have a
255-ish limit on *all* path, relative or absolute.
