zle patch 1

[gwing@primenet.com.au]

Heyla,
  this is a patch on 3.0.3-test3 for "redisplay" bug Zoltan mentioned.
  I'm not a user of multiline prompts so I haven't done extensive testing of
  this.  Anyone who knows about prompt generation may want to check my
  counting of lines in a prompt.

Problems being (re)checked:
   2726/2760 (Robert F Tobler) - problem on Sun - can't duplicate yet.
   NeXTStep TERMCAP entry

Bugs being fixed:
   Coredump on 2 line terminal when using long status line.
