Allow functions in a module to be symlinks

Add the '-' flag to the function glob which makes the other flag test
against the target of the symlink, and not the symlink itself.

When using rcm (https://github.com/thoughtbot/rcm), the function files
are symlinked by default, but the current glob excludes them by
targeting normal files (with the '.' flag).
