PATCH add zle_highlight to variables index

PATCH add zle_highlight to variables index

[Bart Schaefer]

As an aside I noticed that for several variables there is more than one
index entry with the exact same key text, e.g. vindex(histchars, use of)
appears more than once.  This means that one of the index entries gets
tagged with <1> and some versions of the info browser won't find that
entry in an index search.  Is it worth trying to eliminate duplicate
index keys?
