Here's a related idea/suggestion which adds indentation to the output
of _complete_debug.  There's no convenient way to produce ${(%):-%e}
spaces for arbitrary depths without turning on promptsubst, so this
generates a bunch of %N(e. .) expressions and glues them together.
If completion goes more than 20 function calls deep there's probably
something wrong anyway.

I couldn't decide whether to put the indentation after the leading "+"
or before it.  This has it before.

(This is another one I won't commit without positive feedback.)
