What?!?!?   Ok, i would like context in grep, but i'll live without it.
Context diffs, however are a different matter.  There isn't an easy way
to generate them with diff/context (the first character of every line is
produced as part of the diff).  Context diffs are useful for patches, and
having a tool to generate them is necessary.  They're a logical improvement
to diff that is more than just context around the changes.

If you're fixing grep fine, but don't break diff while you're at it.
