No, that sounds like a very reasonable suggestion.  Especially given
that the redirection destination is overwritten immediately after.

In general tests should not have to squelch their standard error
output with 2>/dev/null; that is a job for the test harness, and
they will be shown in the output of "./t3600-rm -v" to serve as
anchor point while finding where a test goes wrong, which is a good
thing.
