I do prefer the new names. They are long, but how often will someone
have to type it? In this case it's better to be descriptive than to be
short. (I wonder if adding two letters would improve readability
further: GIT_PS1_HIDE_WHEN_PWD_IGNORED and bash.hideWhenPwdIgnored.)
To avoid scaring people who might not want this feature enabled, I
recommend changing the subject line to something like this:
git-prompt.sh: Option to hide prompt for ignored pwd

As mentioned in my previous email, I would prefer the code to follow the
behavior of the other config variables (the environment variable has to
be set *and* the config variable has to be non-false).

Rather than:
[ -n "$(git check-ignore .)" ]
I would prefer:
git check-ignore -q .
For example:
if [ -n "${GIT_PS1_HIDE_ON_IGNORED_PWD}" ] &&
[ "$(git config --bool bash.hideOnIgnoredPwd)" != "false" ] &&
git check-ignore -q .
then
