[Rd] ACM license link broken

[Ben Bolker]

The URL listed under
https://svn.r-project.org/R/trunk/share/licenses/license.db for the ACM
license,

http://www.acm.org/publications/policies/softwarecrnotice ,

gives a 404 error.  I think this should be replaced by

https://www.acm.org/publications/policies/software-copyright-notice

?  For what it's worth, the original page did exist as recently as 5
April 2016:

https://web.archive.org/web/20160405100845/http://www.acm.org/publications/policies/softwarecrnotice/

  Suggestions for where/to whom to report this?  R-bugzilla?
cran at r-project.org?  Here?

  cheers
