7e6cabd06e Renumber copyright clause 4 
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

7853af48f5 Allow <blank>s to be used to separate tab stop positions with the -t 
argument, not just ASCII space characters and commas. Don't count
non-printing characters when determining column position.

dd646660ba Some minor nits exposed by the Open Group's VSC Lite verification suite: 
- When an error occurs processing one file, we must continue to process
  the remaining files.
- Convert trailing whitespace to tabs as appropriate.
- Align backspace handling with what the verification suite expects.

fb16fb2f87 Add the -t option, which allows tab stop positions to be specified similarly 
to the way expand(1) allows. This brings unexpand(1) up to SUSv3 conformance,
and it now passes all relevant parts of the GNU textutils test suite.
