Even if -w didn't exist, `git blame` can find previous modifications,
it's not just a tool to find the last one, so it wouldn't be
"useless".

You can tell it to start from the previous commit that made modifications:

    git blame 6ab65fae7a~ -L12,35 Completion/Unix/Command/_make

And you can of course list *all* the previous modifications to those lines:

    git log -L12,35:Completion/Unix/Command/_make

I've sent many patches like this one to the git project itself, so
presumably git has no trouble with them.

Ultimately it's up to you (the developers). Do you want to have
inconsistent whitespaces forever (or at least until somebody modifies
those lines, which seems to happen every 5 years)? Or would you rather
have it clean now?

Personally, sometimes I use ts=2 in shell scripts, so it's very
annoying to see those badly indented lines, but your mileage may vary.

Cheers.
