} compstate[quote] and compstate[quoting] indicate if it is in `...` but
} how can it tell it's in $(...)?

Hmm, at the moment perhaps it doesn't, but it could look at $LBUFFER to
find out.

} The level of nesting would also be useful.

It should be easy to add a special parameter that gives the same info
as the %_ prompt expansion.  I tried ${(%):-%_} but (not surprisingly)
the parser stack isn't "live" during the execution of the completion
function.

The problem is that you end up with too many layers of autoremovable
suffixes.  When completing a path name within backticks, you can't
get both the trailing / on a directory name and the trailing backtick.

} Also, without multios the closing
} bracket of $(<...) should always be completed.

It would have to be an autoremovable suffix, too; `echo $(<file wc)' is
a silly example of why.
