Regarding writing "one-sentence-per-line", I've noticed that style before in LaTeX. While I don't use that style, one advantage that I like is the ability to include comments on the sentence level in LaTeX.

So instead of this:

  First sentence. Second sentence. % Comment on first sentence.

I can write:

  First sentence. % Comment on first sentence.
  Second sentence.

(Of course, one could define a new TeX macro that doesn't display anything to add comments anywhere in-line. That's not as readable, though.)

I've also read that one-sentence-per-line works better with diff programs, but I haven't had any problems with the program meld, so this isn't convincing to me. The advantage the linked article mentions in terms of rearranging sentences also is worth considering, though I haven't found the normal way to be that bad so I'm not convinced by that either.
