I don't see it, either in the code or in the output. I believe that's

If you're going to use DESCRIPTIONS, be aware that it contains multiple
lines, and the number may vary. There's one line for each unique
description following an <a href=...> to the matched document. If you
use this, you'd need to follow it with a special code you'd scan for to
indicate the end of the list.

Apart from that, the only other variables I could see that would contain
newline characters are the ones that contain the select lists, e.g.
FORMAT, METHOD & SORT, which you likely wouldn't use in PHP anyway.
If you do use them, again you'd need to use a special end of list code.

They should all be in hts_templates.html! If you know of some that are
missing (or missplaced) please let us know.
