+ * Flush a line of text. A "line" is loosely defined as being something

+ * broken apart by newlines getting there. A line can also be a
+ * fragment of a columnar list.
+ *
+ * Specifically, a line is whatever's in p->buf of length p->col, which
+ * is zeroed after this function returns.
+ *
+ * The usage of termp:flags is as follows:
+ *
+ * - TERMP_NOLPAD: when beginning to write the line, don't left-pad the
+ * offset value. This is useful when doing columnar lists where the
+ * prior column has right-padded.
+ *
+ * - TERMP_NOBREAK: this is the most important and is used when making
+ * columns. In short: don't print a newline and instead pad to the
+ * right margin. Used in conjunction with TERMP_NOLPAD.
+ *
+ * - TERMP_TWOSPACE: when padding, make sure there are at least two
+ * space characters of padding. Otherwise, rather break the line.
+ *
+ * - TERMP_DANGLE: don't newline when TERMP_NOBREAK is specified and
+ * the line is overrun, and don't pad-right if it's underrun.
+ *
+ * - TERMP_HANG: like TERMP_DANGLE, but doesn't newline when
+ * overruning, instead save the position and continue at that point
+ * when the next invocation.
+ *
+ * In-line line breaking:
+ *
+ * If TERMP_NOBREAK is specified and the line overruns the right
+ * margin, it will break and pad-right to the right margin after
+ * writing. If maxrmargin is violated, it will break and continue
+ * writing from the right-margin, which will lead to the above
+ * scenario upon exit.
+ *
+ * Otherwise, the line will break at the right margin. Extremely long
+ * lines will cause the system to emit a warning (TODO: hyphenate, if
+ * possible).
+ *
+ * FIXME: newline breaks occur (in groff) also occur when a single
+ * space follows a NOBREAK (try `Bl -tag')
+ *
+ * FIXME: there's a newline error where a `Bl -diag' will have a
+ * trailing newline if the line is exactly 73 chars long.
