It sounds like a problem in mlterm, e.g., in the way it stores the "ut"
(terminfo "bce") capability.  It doesn't appear to read the ncurses
terminal database, which (since bce worked when I tested it) says it
does back-color-erase, while the compiled-in termcap says it does not.

If the mlterm package changed that ut-default setting, then providing your
own termcap settings may have reset the behavior to match the compiled-in
NON-ut default.
