fix bug #474:

0000474: vi crashes often

problem was that the buffer used for "." command ("last_modifying_cmd")
wasn't being maintined correctly -- the recording code was walking back
over the front of that buffer when a repeatable insert command
included backspacing (e.g. "i\b\b\bfoo").  the fix is to simply
record the backspaces along with the rest of the command.
    
also, cleaned up start_new_cmd_q() slightly.
