I was thinking, in particular, about this snippet from t/test-lib.sh:

    # git sees Windows-style pwd
    pwd () {
        builtin pwd -W
    }

If that's inherited by the subshell used in the test, then I suppose
all is okay, though I think it would not be inherited.

I think it's OK. $() is itself a subshell, and you can find many calls
to FOO=$(pwd) or similar. And in general, functions are inherited in
subshells:

  $ sh -c 'foo() { echo bar; }; (cd .. && foo)'
  bar

They'd have to be or many things in our test suite would break, since we
use test_must_fail, etc, inside subshells.

Yep, thanks for the sanity dose. For some reason, my brain was
off-kilter, thinking that it was running a shell afresh, not just
using a subshell.
