Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
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.
No functional change intended.
This was not broken on architectures such as ARM where char is unsigned.
Also, remove the first non-portable character from the output. POSIX does
not require this, and printing the first byte may yield an invalid byte
sequence with UTF-8.

This option checks for empty pathnames and components starting with '-'.
Our -p option also checks for the latter, which remains the case.
