Resetting PROMPT_START/PROMPT_END on exit

[bradmwilliams]

/fixes #539

The issue seems to be caused by the logic here:

bash-git-prompt/gitprompt.sh

Lines 249 to 272 in 51080c2

	# Do this only once to define PROMPT_START and PROMPT_END
	if [[ -z "${PROMPT_START:+x}" || -z "${PROMPT_END:+x}" ]]; then
	if [[ -z "${GIT_PROMPT_START:+x}" ]] ; then
	if ${_isroot}; then
	PROMPT_START="${GIT_PROMPT_START_ROOT-}"
	else
	PROMPT_START="${GIT_PROMPT_START_USER-}"
	fi
	else
	PROMPT_START="${GIT_PROMPT_START-}"
	fi
	if [[ -z "${GIT_PROMPT_END:+x}" ]] ; then
	if $_isroot; then
	PROMPT_END="${GIT_PROMPT_END_ROOT-}"
	else
	PROMPT_END="${GIT_PROMPT_END_USER-}"
	fi
	else
	PROMPT_END="${GIT_PROMPT_END-}"
	fi
	fi

Basically, the values of both PROMPT_START and PROMPT_END are being set accordingly when entering a git repository, but never being reset to their original values upon exiting.

This PR adds a couple lines to capture the original values of PROMPT_START and PROMPT_END on the way in and then resets the values accordingly on the way out.

Similar findings to #542.

Tested on F-39 and it works as expected.

This is also working for me. I hope this gets merged soon, as it is better than #542, since it handles both start AND end.

It worked for me also, tested on Fedora 39

[Dylan-M]

Yeah, at this point the fix has been verified. We just need it to actually get merged by @magicmonty ;)

Hopefully soon, but in the meantime I just keep manually applying the fix as needed on my systems.

I can confirm this worked for me on Fedora 40.
