141: * - TERMP_NOLPAD: when beginning to write the line, don't left-pad the

148: *
149: * - TERMP_NONOBREAK: don't newline when TERMP_NOBREAK is specified.
150: *
151: * In-line line breaking:
152: *
153: * If TERMP_NOBREAK is specified and the line overruns the right
154: * margin, it will break and pad-right to the right margin after
155: * writing. If maxrmargin is violated, it will break and continue
156: * writing from the right-margin, which will lead to the above
157: * scenario upon exit.
158: *
