Oh, I agree. I meant in a "general version-control sense". I doubt a lot of other version-control systems could do it. Git can, exactly because it's whole-file based, and our deltas are limited.

So it's not that "builtin-grep" is wonderful. It's that _git_ is wonderful, and the builtin-grep just shows one of the end results.

That's why we have killer features. To show off.

(That said, git will slow down a tad too - the pack-file access won't be as optimized for an old version tree, and so you'll seek around some more for the cold-cache case).
