Since find does output directories, and clearly you don't want to grep on
them, why not just do something like
find . ! -type d | xargs grep
To be even safer and work with any file name (containing even newlines),
you actually need to do
find . ! -type d -print0 | xargs -0 grep
So maybe you just want to alias this whole thing :-)
I don't think this a reason to keep GREP_OPTIONS, but like I said I don't
mind if it is kept if at least people are warned about how it might break
