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