Can anyone explain this:
% sh -ec 'f() { return 5 ; } ; if f ; then echo tt ; else echo ff ; fi'
ff
% sh -ec 'f() { return 5 ; : ; } ; if f ; then echo tt ; else echo ff ; fi'
% echo $?
5
If any commands appear after the return statement in a function,
then -e flag triggers untested command failure although function call is
tested with `if' statement.
