He can't, because people like you keep using it.  Also, it's probably
mandated by POSIX.  I can't be bothered to check.

sh's -e is *not* equivalent to perl's use strict.  They do not accomplish
the same goals, nor do they try to.  Using -e in a sh script is the same
as writing  || exit  after every... single... command in the script.
Except for the ones where it isn't the same.  And nobody can guess what
those commands are.  It does not perform extra validations on your code.
It does not help you uncover programmer errors.  It is *nothing at all*
like use strict.
