That's true for the windows explorer, not for TSVN per se.

Yes, urls and paths in error messages are truncated. Because the list
control wouldn't show the error message correctly if they weren't
(because of the before mentioned limitation). But internally, the
strings, paths and urls are *not* truncated in TSVN. Only for UI output
they are.

I seriously doubt that, unless you're trying that on a non-windows OS.
Because those clients have the same limitations that the windows API has.
