[texhax] Positioning that depends on space available in the current line

[Aleksandar Zec]

Arnaud, Lars, Steve,

Many thanks for your code. Works great and it's very educational.

One subquestion. In case (2):

aaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaa
   bbbbbbbbbbbbbbbbbbbbbb

is it possible to have aaa and bbb blocks as two separate paragraphs
instead of one?

Or, if it's not possible, is it possible to insert an optional element
between aaa and bbb block (which doesn't appear in case (1)) of
course. I mean some vertical space of something.
