[PATCH setup 08/10] Fix infinite recursion in grammar for depends

[Jon Turney <jon dot turney at dronecode dot org dot uk>]

Allowing listseparator to be empty allows an infinite recursion in the
versionedpackagelist rule

Also make the comment documenting versionedpackageentry is non-empty
consistent with all other similar comments

Also allow lower-case depends:
