Subject: vared doesn't honour leading escaped separator

[[[
% () { IFS=: vared argv; typeset -p argv } :foo:bar : baz
\:foo\:bar:\::baz
typeset -g -a argv=( '' foo:bar : baz )
% 
]]]

When vared opened, I just pressed <Enter> without changing the line in
any way.  Accordingly, I expected argv not to be changed by the edit.

This is due to the spacesplit() call at the end of bin_vared().

Changing the value of the second parameter (allownull) doesn't fix it,
but does cause «typeset -p argv» not to emit the two single quotes
around the first value (!?).
