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