style: Detabify regen files.

They generate C files.

Bump feature.pm and warnings.pm versions to satisfy cmpVERSION.pl.
I can't get it to easily ignore whitespace, `git diff --name-only`
does not respect the -w flag.

regen_perly.pl is left alone. That would require rebuilding
perly.* which is beyond a simple indentation change.
