Well, this has nothing to do with your bugs, but if you are running
Emacs on a MIPS based machine do modify (I posted a suitable patch)
insdel.c so that gap shifts are done with bcopy and not character by
character.

You will be entirely amazed at the increment in speed, because bcopy
not only is faster with blocks moves, it also does them with the hw
instructions for unaligned word access, which is a large, large win.


Also, enlarge the default gap to a few dozen KBytes to minimize the
number of realloc() calls at the expense of some page table space.
