Yes, it might. I guess it just seems plausible to me that somebody would
expect GIT_TEST_INSTALLED to be as close to the installed experience as
possible. I dunno. I do not use it myself.

At any rate, my point was that for GIT_TEST_INSTALLED, either:

  1. We can use a known-clean set of templates (either our local
     templates/blt, or an even-cleaner empty set).

or

  2. We do not need to specify any template, and it will just use
     whatever it came installed with.

And in either case, we do not have to worry about asking it "where are
your templates?".
