[PATCH] add-zle-hook-widget zle-line-pre-redraw issue



Hooks registered with «add-zle-hook-widget zle-line-pre-redraw $hook»
aren't invoked.  In contrast, hooks registered with zle-line-finish are
invoked.

The reason appears to be that, while in azhw:zle-line-init $WIDGET is
"zle-line-init", in azhw:zle-line-pre-redraw $WIDGET is the name of the
widget the user invoked (e.g., "self-insert"), so the 'zstyle -a' does
not find the registered hooks.

Each of the following alternative patches solves the issue:

The principal differences seem to be which set of globals is
saved/restored or changed/restored; however, which set it should be is
all Greek to me.

Cheers,

Daniel
(I haven't tested the other hook types.)
