It does what the comment implies ("skip if checked already"). Skips a redundant
test_global_state_dir() call that's already been done for that directory. It's
entirely possible that home_dir_for_helpers before was not writable, so it's
possible that $home and $prev are now equal.
Yes the logic was generally left a bit unclean, but it works.
