Is this why bash.showDirtyState and friends aren't checked unless the
corresponding environment variable is set to a non-empty value?
Regardless, it would be nice if the behavior matched the other bash.*
variables (only check the bash.* variable if the corresponding
environment variable is set, and default to true). The following should
fix it:
if [ -n "${GIT_PS1_HIDE_ON_IGNORED_PWD}" ] &&
[ "$(git config --bool bash.hideOnIgnoredPwd)" != "false" ] &&
[ "$(git check-ignore .)" ]
then
