"Cursor is at [beginning, end] of a line" seems to be a pretty common
thing to want to test.  Maybe the zsh/zleparameter module should define
some condition codes so one could write stuff like

	if [[ -bol CURSOR && -eol MARK ]]; then

Aside:  The zsh/complete module defines -prefix -suffix -between and
-after but only -prefix is ever used by the shell code.

Per recent discussion about why add-zle-hook-widget is not suitable for
"non-special" widgets:  Part of the criteria for an action-widget hook
should be that flags on the hook'd widget, such as "is a vi operator",
persist across execution of the hook.
