* pr: For compatibility (also more POSIX compliant): Include default
separator `TAB' when merging lines of full length.
* When POSIXLY_CORRECT is not set, tail -N now accepts more than one file
- argument (but warns that it's not portable), to be consistent with the
- way head -N works. If POSIXLY_CORRECT is set, using two or more file
- arguments with the obsolescent form (-N) evokes an error. To avoid the
- warning or failure, use the POSIX -n N option or the GNU --lines=N option.
