For variables that are only checked with defined(), don't provide

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.

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.

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.
