PATCH: fix for zle line size

PATCH: fix for zle line size

[Peter Stephenson]

Required by my last patch: sizeline() needs to be more flexible because
we may reallocate a line from scratch which we didn't need to do
before.  I saw this as a hang running zcalc; I think it's to do with
an empty history line.
