license.db Bug Report (FSF field for CC 4.0 licenses)

Thanks: now updated in R-devel. We dropped the obsolete and unused CC 2.0 and 3.0 entries, and simplified the OSI and FSF tags to what is needed for the FOSS tag. Best -k
Hi, I noticed some errors in the `FSF` fields in `share/licenses/license.db` for some Creative Commons licenses:
`license.db` should be corrected to:
``` Name: Creative Commons Attribution-ShareAlike 2.0 Generic License Abbrev: CC BY-SA 2.0 FSF: free_and_GPLv3_incompatible
Name: Creative Commons Attribution 4.0 International License Abbrev: CC BY 4.0 FSF: free_and_GPLv3_compatible ( https://www.gnu.org/licenses/license-list.html#ccby)
Name: Creative Commons Attribution-ShareAlike 4.0 International License Abbrev: CC BY-SA 4.0 FSF: free_and_GPLv3_compatible ( https://www.gnu.org/licenses/license-list.html#ccbysa) ```
* According to the current version of https://www.gnu.org/licenses/license-list.html the FSF considers the CC BY 4.0 license "compatible with all versions of the GNU GPL" and the CC BY-SA 4.0 license "one-way compatible with the GNU GPL version 3: this means you may license your modified versions of CC BY-SA 4.0 materials under GNU GPL version 3". * Note Creative Commons explicitly declared GPL-3 a "BY-SA Compatible License" for version 4.0 on October 8th, 2015: https://creativecommons.org/share-your-work/licensing-considerations/compatible-licenses * In a previous version of the FSF license website available on web archives (e.g. http://web.archive.org/web/20150124042152/https://www.gnu.org/licenses/license-list.html#OtherLicenses) the FSF explicitly considered the earlier CC BY 2.0 and CC BY-SA 2.0 licenses incompatible with the GNU GPL licenses.
I'm unsure whether the URL for the `FSF` field for the CC BY-SA 2.0 license should point to such a Web Archived link or simply be stripped as I suggested above. However the current version of https://www.gnu.org/licenses/license-list.html#ccbysa no longer mentions the CC BY-SA 2.0 license nor its incompatibility with the GPL license and hence it should be updated in some fashion.
Best,
Trevor
