Oh right, the bit that unzips/rezips .whl files cannot easily be done
from a snippet, so better keep it as a phase.

Deleting *.exe can be done from a snippet though.

BTW, the patch reads:

   (find-files "Lib/distutils/command" ".*.exe$")

but the regexp should be:

  "\\.exe$"

(“.*” is unnecessary, but the dot before “exe” must be protected.)

Likewise for:

  (find-files "Lib/ensurepip" ".*.whl$")

Thanks,
Ludo’.
