Well, we have a decision to make. If we think it's a bug that transaction
names can be reused, then FSFS repositories created with Subversion 1.4 have
this bug. I don't understand that ramifications of txn reuse (which is why
I've Cc: Blair -- I remember this topic coming up on the list and being
driven by him).

If we'd rather ignore the problem, it's easy enough to make the code bail
out when testing FSFS with 1.4-era repository versions. I'm happy to make
that change -- just let me know.
