because we are not doing anything about a failure of $(pwd), other
than skipping the export. If we were failing the entire thing, it
would be a different story, but at this point of the test, it is
unreasonable to do something like:
TEST_DIRECTORY=$(pwd)/../../../t &&
export TEST_DIRECTORY || exit $?
anyway.

Similarly, as we do not do anything if the assignment to GIT_DIR
fails here, just like we ignore any failure from assignment to
force,
GIT_DIR="$url/.git"
export GIT_DIR
would be sufficient.
The logic before the "mkdir -p" of this script may want to be
cleaned up (can you tell how "if $refspec is empty, set prefix=refs"
makes any sense, and what its implications are, without thinking for
more than 10 seconds?), but that is clearly a separate topic [*1*].

This one does care about failures. I'd rather have these on
separate lines, i.e.
