Example of using "-command-line-" context?

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

The _normal function installs itself with "#compdef -command-line-" but, as
the documentation explains, nothing uses that context.

This must be intended as an entry point for user-defined widgets that don't
want to invoke the entire compsys machinery?  If not that, then what?  It's
mentioned in http://www.zsh.org/mla/workers/2000/msg02232.html as a helper
for completing after the "zse" (zstyle edit) function, but there was no
follow-up showing it actually put to use.
