I wouldn't mind the intial idea: just the abbreviated top of three hash.

I was, next, going to write that CONFIG_LOCALVERSION_AUTO already exists
for that, but LOCALVERSION_AUTO calls scripts/setlocalversion these days
and that is what I'd prefer to avoid.  [SIGH]

Shows how long it has been since I last used it.  I stopped using it
when I was maintaining my .config in git.  Now I maintain .config in a
separate git repo, for the express purpose of avoiding a merge (rather
than a fast forward) when I run git pull.  Something that a local edit
of scripts/setlocalversion will, of course, prevent.

Anyone up for a CONFIG_LOCALVERSION_AUTO_DO_NOT_BOTHER_WITH_DIRTY? ☺
