[Nmh-workers] Search order of the lines in .mh_profile |

Right now, all but the first line, of .mh_profile, assigning a given variable
is silently ignored. This seems wrong to me. All but the last assignment
should be ignored. Maybe an admonish message should be issued then.
But multiple assignment to the same variable, is almost always a user error.
So maybe the program (i.e. pretty much every nmh command) should then abort.
