Well, yes, actually... but zsh/functions is fine.

FUNCTIONS_INSTALL (as I've called it) was easy to add.  I've made it get
set by default to all the Completion subdirectories, and Zftp/* gets added
if dynamic is turned on, but you can override it in configure or make.

Is FUNCTIONS_EXCLUDE important?  Things get excluded anyway unless they're
in FUNCTIONS_INSTALL, so "make install FUNCTIONS_INSTALL='Core/* Base/*
Builtins/* Users/_configure'" will do what you want.  Excluding probably
means looping over the exclusion variable inside the $FUNCTIONS_INSTALL
loop, which I'd like to avoid.

The stuff only gets put into fpath when you run compinit because it knows
the path to compinit, which it wouldn't if it were a function; you'd have
to give it the -f option.  So the nettle of deciding where the things are
has to be grasped anyway.  But this is all supposed to be handled
seamlessly by running compinstall.  At least with the function installation
stuff, you get a sensible default $fpath, which compinstall will check.

One thing's been niggling at me:  if there's a central function repository,
and the user has their own functions, then compinit.dump has to be somewhere
else, probably not in the same directory as compinit.  It looks like
compinit will need to be a bit smarter about working this out.
