41 * colcrt - replaces col for crts with new nroff esp. when using tbl.
42 * Bill Joy UCB July 14, 1977
44 * This filter uses a screen buffer, 267 half-lines by 132 columns.
45 * It interprets the up and down sequences generated by the new
46 * nroff when used with tbl and by \u \d and \r.
47 * General overstriking doesn't work correctly.
48 * Underlining is split onto multiple lines, etc.
50 * Option - suppresses all underlining.
51 * Option -2 forces printing of all half lines.
