Thanks.  I avoid sed, tr, etc., as I'm sure you can tell.

I don't see a POSIX program to make a temp file, so it might
be best to write a trivial program using mktemp(3).  But
that's beyond what I want to do now.  Especially given that,
if they're not unique without the substitution, a backup
message might be lost anyway.  I'll note the deficiencies it
in the documentation.
