The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
Initially, only tag files that use BSD 4-Clause "Original" license.

This commit is non-functional from a code-execution perspective, but
pr(1) now compiles WARNS=6 clean.
When you ask pr to use form feeds at the end of pages and specify a page
length and tell pr to not put the fancy headers and footers on each
pages, then pr will not separate the pages with a form feed.
Closes PR: bin/1237
