Vi command mode and end-of-line; ZWC('\n') ?

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

That thread about end-of-line not working as a "bindkey -a" widget annoys
me for some reason.  I started looking through zle_move.c and discovered
that in a few places we compare

	zleline[zlecs] == ZWC('\n')

but in more places we simply do

	zleline[pos] == '\n'
	zleline[zlecs - 1] != '\n'

There's even one comment about the latter

	/* works OK with combining chars since '\n' must be on its own */

So which is it?  Should we be using ZWC() or not?

Meanwhile, any objection to this?
