I assume it's a bug (I recall that it's supposed to fill with spaces).

I can see what's involved in implementing it (at the moment unsure of the 
ease of implementation).

By analogy with ^A-p, which is one of the calls on doput() - see 
rectputafter in cmdtbl and line.c, the insert/append stuff is implemented 
by ins_n_times(). But the latter may not work with regions (I don't see 
any sign of it in insert.c where I'd expect, so I assume it does not). 
If it did, then adding predefined bindings is easy.
