Bug#272548: drsync: assumes second argument is a directory
Here we see that a local test that would work with plain rsync,
$ date>a; rsync a b
doesn't work with drsync:
$ date>a; drsync.pl --state-file=c a b
sh: line 1: cd: b: No such file or directory
Executing: rsync --update --existing --rsh=rsh a b
It turns out that drsync assumes the second argument is a directory --
so it is not truly using the same rules as rsync.
We were doing local tests to get familiar with drsync before spending
money on modem calls.
