WARNING:  Beware of Feature

Some of your "bugs" are really "features" because of the way VI does
things.  The reason the search /3*[a-z]/ moves you two characters
if you're sitting on a long string of text, is that vi doesn't want
to re-find the last found occurance of this, so it moves you right
before starting the search.  It should move right one character, but
apparently someone made it move 2 for some reason.

Also, things with "c*" always try to match the longest string on a
line; this tends to do counter-intuitive things sometimes.  (I suppose
that depends on what your intuition says.)
