My interpretation of the GFDL is that Wikipedia is far from conforming, so, to make it easier for them to use my material without having to negotiate new licensing terms with me:
Licensing rights granted to Wikimedia Foundation
I grant non-exclusive permission for the Wikimedia Foundation Inc. to relicense my text contributions under any copyleft license that it chooses, provided it maintains the free and open spirit of the GFDL. This permission acknowledges that future licensing needs of the Wikimedia projects may need adapting in unforeseen fashions to facilitate other uses, formats, and locations. It is given for as long as this banner remains.
My understanding is that obvious edits aren't copyrightable, but to the extent that minor edits might be considered copyrightable, and given that the UK doesn't have a concept of abandoning to the public domain:
All rights released to all minor edits
I agree to release all rights, unless otherwise stated, to all my English Wikipedia text contributions marked as minor edits, enabling anyone to use them for any purpose. Please be aware that other contributors might not do the same, so if you want to freely use my minor edit contributions, please check the multi-licensing guide.
The above two notices apply retrospectively from my first contribution.
