Hi guys,

I'd like to suggest a minor enhancement for "lisp/progmodes/grep.el".

This patch is to let you input the cursor position symbol automatically
into minibuffer command line. I think it makes us easier to use "grep-find"
function.

Also attached is the images for showing how to work "grep-find" function
before and after this patch.

I confirmed that it is possible to apply this patch both 22.1 and 22.2 version.

Thanks,
- Kazuo YAGI
