It seems that OMIT_SPARSESTATE would have the same issue.

	if [ -z "${GIT_PS1_COMPRESSSPARSESTATE}" ] &&
	   [ -z "${GIT_PS1_OMITSPARSESTATE}" ] &&

all coming from afda36db (git-prompt: include sparsity state as
well, 2020-06-21).

But I think we have already seen the fix in 5c0cbdb1 (git-prompt:
work under set -u, 2021-05-13), which may or may not appear in the
upcoming release.

There still are unprotected mentions of GIT_PS1_SHOWUPSTREAM even
with that fix, though.
