Now try these:
file:///C:/Program%2520files/nonexistent
file:///C:/Program%20files/nonexistent

You see: the svn file:/// urls always point to (locally) non-existing
paths since they're inside the repository (which has no corresponding
path locally).
Windows can deal with spaces in such an url, so it checks the existence
of such local paths to find out which path was meant with the url
(escaped or not). But that fails terribly if the path doesn't exist.

So escaped file:/// urls just don't work if the path there doesn't
really exist.

TSVN escapes all urls properly, even file:/// ones.
