I have been through a few different man pages for various shells, and I can't
seem to
find an explanation for ${name-word}. I have run across ${name:-word} for some
shells, which say that word will be assigned to name (and used) if name is null
or
unset. However, my own tests with ${name-word} result in word being used ONLY
if
name is unset. If name is null, then null is used.
This behavior should be explicitly documented in the procmailrc man page.
WTFM!!!
