I agree, original version only we already have the SPDX Identifier.

It's a difficult task with BSD licenses and I found no original source yet.
Official information from Berkeley University:
http://ipira.berkeley.edu/
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

Other sources or information:
http://www.linfo.org/bsdlicense.html
http://opensource.org/licenses/BSD-2-Clause
http://www.freebsd.org/copyright/license.html

should I rebase without an URL for BSD-2-Clause as long as we have the
license in text form anyway?
