No, it is an argument against making the process of renormalization
more painful than it has to be (and against piggy-backing in general).
It is kindest to have a flag day and yank the carriage returns off all
at once like a bandage.

Only if they cross the revision where renormalization occurred.

This looks more sane.  Ident strings usually touch only a few lines.

Wouldn’t something like

 /foo.c -ident has_foreign_ident

work?  (Thanks for fixing that attributes macro processing bug, btw.)

Can’t you include a hooks/pre-commit file and a HACKING file: "copy
this file to .git/hooks if you want your patches to be accepted"?

Thanks for your hard work,
