applying broadcasting to function inputs

[Ben Abbott]

Jordi,

I've attached a changeset for __line__.m (for the bug linked to below).

        https://savannah.gnu.org/bugs/index.php?35216

Any concerns about using your recent broadcast feature to fix this?

As there are many place in the code needing similar solutions, should a 
function be written in order to avoid code duplication ?
