Public bug reported:

Calling erase invalidates the iterator passed to it and therefore, using
that iterator again (like incrementing or dereferencing or passing it to
a function) isn't allowed.

The patch below also provides greater efficiency, since the elements
that are not being removed don't move as much if lines are removed from
the middle.

** Affects: mudlet
     Importance: Undecided
         Status: New


** Tags: crash perf

** Patch added: "Replace with the two iterator version of erase instead of looping."
