I apologize for replying to my own message multiple times.

I just realized that what I suggested may not work. Consider this code:

    print -r -- ${(%):-'%{hello%}'}

Currently it is equivalent to this:

    print -r -- 'hello'

However, if percent expansion starts inserting \001 and \002, the same
code will be equivalent to this:

    print -r -- $'\001hello\002'

This may be undesirable.

The patch by Felipe, as it stands, doesn't have this problem.
