+ The PWB/Unix <STRONG>tabs</STRONG> utility returned in System III (1980), and used
+ built-in tables, rather than the terminal database, to support a half-
+ dozen hardcopy terminal (printer) types. It also had built-in logic to
+ support setting the left margin, as well as a feature for copying the
+ tab settings from a file.
+
+ Versions of the program in later releases of AT&T Unix, such as SVr4,
+ added support for the terminal database, but retained the tables to
+ support the printers. By this time, System V <STRONG>tput</STRONG> had incorporated the
+ tab stop initialization feature of BSD's <STRONG>tset</STRONG> from 1982, but employed
+ the <EM>terminfo</EM> database to do so.
+
+ The <STRONG>+m</STRONG> option was documented in the POSIX Base Specifications Issue 5
+ (Unix98, 1997), then omitted in Issue 6 (Unix03, 2004) without express
+ motivation, though an introductory comment "and optionally adjusts the
+ margin" remains, overlooked in the removal. The <STRONG>tabs</STRONG> utility
+ documented in Issues 6 and later has no mechanism for setting margins.
+ The <STRONG>+m</STRONG> option in <EM>ncurses</EM> <STRONG>tabs</STRONG> differs from the SVr4 feature by using
+ terminal capabilities rather than built-in tables.
