|

|
* - TERMP_NOBREAK: Do not break the output line at the right margin, |
|
* but only at the max right margin. Also, do not break the output |
|
* line at the end of the chunk, such that the next call can pad to |

* the next column. However, if less than p->trailspace blanks, |

|
* will be broken. |
|
* - TERMP_BRTRSP: Consider trailing whitespace significant |
|
* when deciding whether the chunk fits or not. |
|
* - TERMP_BRIND: If the chunk does not fit and the output line has |
|
* to be broken, start the next line at the right margin instead |
|
* of at the offset. Used together with TERMP_NOBREAK for the tags |
|
* in various kinds of tagged lists. |
|
* - TERMP_HANG: Do not break the output line at the right margin, |
|
* append the next chunk after it even if this one is too long. |
|
* To be used together with TERMP_NOBREAK. |
|
* - TERMP_NOPAD: Start writing at the current position, |
