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

* that should be followed by a newline, regardless of whether it's |
|
* 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 variables TERMP_NOLPAD, TERMP_LITERAL and TERMP_NOBREAK are of |
|
* critical importance here. Their behaviour 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_NONOBREAK: don't newline when TERMP_NOBREAK is specified. |
|
* |
|
* 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). |
