in other words:
If someone talls me that they want ``grep pat dirname'' to go recursively
through the tree, I suggest him to set ``GREP_OPTIONS=-drecurse''.
Is it insane that they require that
foo | grep pat
still works?
Of course, one can imagine that we add a fouth possibility besides
`read', `skip' and `recurse':
--directories=recurdir ... recurse directories; additionally when
no filename is given, search current directory
and make `-r' shortcut for this.
Then ``grep -r pat'' would search current dir.
And we would have to teach people to use GREP_OPTIONS=-drecurse
insted of GREP_OPTIONS=-r .
But I beleive this solution would be too complicated to be worth it.
