this is a very slippery slope
"but I only want
to-follow-symlinks/to-not-follow-symlinks/to-not-cross-filesystems/executables/non-executables/regular-files/regular-files-i-own..."
and before you know it every -r command has glommed on a chunk of find
for the simple case a 21st century user should use
set --globstar
grep **/*.[ch]
my_foo **
and all *.[ch] under . will be grepped
for too large an arg list use
command -x foo **-PATTERN
for detailed filtering use tw
*if* the only request for -r, and *just* -r, would be to add it to grep,
I might be persuaded to do it
