I'm not sure it would be a good use of time at GitTogether to do something
whose spec is pretty much self-evident (essentially for this one it boils
down to "define what are the 'funny' bytes, and list the protocols
supported by svn, and come up with paths with funny bytes in it and
see what libsvn-perl gives to the underlying svn library, and what the svn
library does over the wire"). Ongoiong "fix start-up sequence around
worktree area" might be a better fit; I dunno.

Item 3. above disturbs me. Do you mean that in:
https://sucs.org/~welshbyte/svn/backuptool/trunk/foo~bar.txt
the two tildes might have to be sent to libsvn-perl differently?
Even if that is the case, I am inclined suggest taking the patch in the
meantime as an interim workaround, with the understanding that we know the
patch improves the situation for the tilde before welshbyte and even
though we do not know if the patch regresses for the latter one between
foo and bar, it would be much rarer to have tilde in such places.
Care to come up with an updated log message?
