Re: [PATCH] i18n: make GETTEXT_POISON a runtime option

Jeff King [off-list ref] writes:

but then you lose the default handling. I think if we added a new
option, it would either be:

  # interpret a value directly; use default on empty, I guess?
  git config --default=false --type=bool --interpret-value "$GIT_WHATEVER_ENV"

or

  # less flexible, but the --default semantics are more obvious
  git config --default=false --type=bool --get-env GIT_WHATEVER_ENV

Yeah, my thinko.  The latter would be closer to what this patch
wants to have, but obviously the former would be more flexible and
useful in wider context.  Both have the "Huh?" factor---what they
are doing has little to do with "config", but I did not think of a
better kitchen-sink (and our default kitchen-sink "rev-parse" is
even further than "config", I would think, for this one).
