I agree. If as a user I care to set my environment in some specific
way, I expect other programs to honour my settings.
If all my scripts were resetting PATH and hardcoding #!/bin/sh, it
would be much harder to install and use newer versions of programs

Would it be better to set DEFEDITOR to the real path which was tested
elif [ -x /usr/contrib/bin/jove ]; then
DEFEDITOR=/usr/contrib/bin/jove # instead of just jove
It would seem more robust to me, since /usr/contrib/bin is not
necessarily in PATH.

Would a fix prepending system paths if user = root be a better
Or even reset PATH completely?
if [ $(/usr/bin/id -u) -eq 0 -o $(/usr/bin/id -r) -eq 0 ]; then
