Subject: [PATCH] term: print: reset combining characters for this cell

This is the *only* place combining characters are reset. In
particular, we do *not* reset them in a normal cell erase.

This is a performance design decision - clearing the combining
characters in erase is way too slow.

This way, we clear it only when we *have* to. Anything looking at the
combining characters must first ensure the base character is not 0.
