Fmtutil always return 0

[Denis Barbier]

Hi,

the fmtutil script always return 0, which is confusing for script
writers.

I would like to replace in all teTeX scripts traps like
   trap 'cd /; ...some commands...; exit 0' 0 1 2 6 13 15
by
   trap 'rc=$?; cd /; ...some commands...; exit $rc' 0 1 2 6 13 15

Is there a reason not to proceed this way?

Denis
