It is, but there is no shell involved, and assuming that a shell is being
used is invalid. Adding backslash escaping now could potentially screw up
anyone currently passing a backslash in their existing rsync scripts (a
small group of people, but probably non-zero). It's tempting to go ahead
and do this, but I think I'll just leave it as it is.

If you want to work around that buggy escaping library, you could change
"ssh" to "ssh-nobs" and put the following into that file:

#!/usr/bin/perl
exec 'ssh', map { s/\\(.)/$1/g; $_ } @ARGV;

That adds backslash removal on the way to the ssh.  It does not allow you
to backslash escape spaces, though, but someone could extend the script to
support that.
