Yes, it's a bit more difficult than it should be.  Furthermore, for most
users installing versions as well separated as 3.1.6 and 3.1.7 will be, the
position will be even worse, even if the pace of change of this area of the
code slows down in future.  So this adds the version.

I hope the choice of path (default
`/usr/local/share/zsh/functions/3.1.6-dev-14', mutatis mutandis) is
rational.  The version-specific bit comes last, as with the module path,
and the `share' remains present, despite the version-dependence, because it
refers to the absence of machine-dependence (it worried me at first, but
actually I've just noticed Emacs does exactly the same with its lisp code).
Indeed, this will make it easier to share functions across architectures
potentially running different versions of the shell.

 You can control the functions which get installed by setting
 FUNCTIONS_INSTALL, either when running configure (e.g.
