Junio!  Thanks for that recipe.

I suspected there must be some way to employ git-apply's whitespace=fix
feature to ws-normalize my code, but I was clueless how to do that.  I
wound up cobbling together a python script that reimplements the same
fixes (hopefully).

I wish this (the git-apply trick) was documented somewhere and/or made
more prominent.  Is it, and I have also overlooked it?

This is what I want:

   git fix-whitespace             # fix new ws errors in workdir
   git fix-whitespace --all       # fix all ws errors in workdir
   git fix-whitespace foo         # fix new ws errors since foo
   git fix-whitespace --cached    # fix new ws errors in the index
   etc.

Is this already implemented somewhere in the git porcelain?
