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