Submiting a tweak to 'find' where?

[David Snyder <dasnyderx@yahoo.com>]

To all and sundry,

I've coded some new options to the program find: -older, -aolder, and
-colder.  Basically, it's just -newer (and the -a and -c newers) with
the comparison operator reversed (from '>' to '<').  I thought it would
be useful to find (and possibly clean out cruft) with a cruft-cleaning
script (something I haven't coded up yet).  Where should I submit these
changes?  On tech@, misc@, or somewhere else?  Also, should I submit it
as a full source-code tarball or will a unified diff do (there's also
some gramatical errors I fixed in one of the files)?  Thanks.

David
