Thanks for checking. It turns out that the problem I referred to below
was not related to the length of the filenames at all - that was a
coincidence.
The reason for for the "can't open file" during the checkout is that
the repository (built from a dump file produced by vss2svn) had some
directories with filenames that differed only in case, for example, both
"bar/Foo" and "bar/FOO". With the case insensitive windows filesystems,
the complaint really referred to the fact that after the client moved
"Foo" out of the bar/.svn/tmp/text-base directory, it was surprised and
disappointed that it couldn't find "FOO" there a moment later.
Now the explanation is here in the mailing list archives for posterity.
