the only time I ever wanted this kind of feature
is for grepping through sourcecode.
ron's modified grep is now installed on my boxes;
there is a precident (diff -r).
If you're like me, you often have a bunch of object files
in your source tree and you usually want to enumerate
files, filter out some of the names and then grep the resulting
list... ie. recursive grep will grep a bunch of files you
dont want to grep... something like:
grep -n foo `{f|grep '\.c'}
will go much faster (assuming /bin/f enumerates filenames).
