This turned out to be a little more involved than I thought, but I changed
things so that command -p won't change the $PATH. If you want to have a
command-specific version of $PATH, you can use the temporary environment
for that, but there's no way to use command -p without modifying $PATH in
bash-4.3 and previous versions.
This uncovered a bug, too: if you use command -p with a temporary environment
assignment to PATH, that tempenv assignment is what persists after the
command completes. My changes fix that also.
This will be in the next release of bash.
