Hmm, you can use find command to mimic -r or -d behavior and
getopt(s) to cope with -iv.   Do you have a good idea to
do a proper quoting for -e options passed to grep, for instance,
zgrep -e 'foo bar' -e '".*"' ?

TO_REMOVE lines for z{,e,f}grep and their manpages should be removed
otherwise you're going to remove them when you do `make upgrade', or
are we talking about something else?

Cheers.
