Hmm.  I tend to think of it exactly the opposite way -- if I set errexit,
I generally want it to continue to apply down through functions I call,
because of exactly the circumstances you note -- scripts run from make,
which uses -e when it invokes the shell.

If emacs vc didn't have a tendency to create files with names that look
like basename~version~ it'd be less of a problem, because I already
habitually quote carats (some old Bourne shells read carat as pipe, from
