I wrote that up, but then I didn't like it.  The use of 'char *'
should be reserved for host-format character strings, but it looks to
me like LA_PRINT_STRING expects a string in the target format.  (Not
that the interface documentation offers much help here.)  Look at the
way c_printstr unpacks the string character by character using
extract_unsigned_integer.  Look at the way LA_EMIT_CHAR is responsible
for calling target_char_to_host.

If folks agree, then I'll make the comments in language.h clearer, and
try to finish off this change.
