Correct inconsistency in use/nonuse of definite article before
non-attributive uses of *GPLvn by opting for typical present-day FSF
usage (with no article). I believe the FSF tends to use "GPLvn"
(rather than "the GPLvn") when the license is referred to by
abbreviation and is not prefixed by "GNU". This can be confirmed by
analysis of usage on the fsf.org website.
