grep: default file if -r is used

[Koblinger Egmont]

Hi,

I quite often type grep to look for a particular string in a huge
directory tree, e.g. a source code. So I type something like this:
grep -rl pattern .

I found that in many cases I forget to type that '.' at the end.
Especially since the pattern is often copy-pasted from the mouse, I have
to put my fingers properly back on the keyboard to press Space+Dot+Enter
instead of just hitting the keypad Enter next to the mouse (or maybe the
seletion buffer already contains a newline).

And then grep starts to recursively read stdin... But hey, this doesn't
make too much sense. It's quite obvious IMHO that if I told "-r" to grep
then I want it to scan a directory, most likely the current one if I
forgot to tell it.

So my feature request is: if "-r" or an equivalent option is given to
grep, and the file argument is omitted, it should default to "." rather
than stdin.


thx,

Egmont
