One-line rendering

[elibarzilay]

In two very different contexts I ran into a need for a "lightweight" rendering of just one line. I hacked this with a small wrapper that checks that I get a document with a single paragraph and if so, replace that paragraph by the list of things in it. Wouldn't it be useful to add something that makes it easier to get this functionality, or maybe I'm missing something obvious?

(The other context I had this is via the C code, but it's the same issue.)
