No, there's actually another option. Bruce posted a patch for reverting
to 7.2-behaviour (well, sort of...); I currently cannot find the
original message, but here's the relevant bit:

Note however, that regression tests for 7.3.x will fail, as there are
explicit tests for zero-length strings to cause an error. That need not
worry you, though. We're currently running 7.3.4 with this patch and it
works like a charm.
