Well, if I reuse an old presentation I usually use the old pdf. > I generally put displays in separate paragraphs, I rarely use > autofill[fn:1] and I'm happy to do M-q on individual paragraphs instead, > but if I happen to do it on the wrong paragraph (backtraces, code > fragments, displayed equations), undo is easy enough. The problem with that is that a displayed equation should NOT start a new paragraph (in the generated LaTeX file). This is because if it does then LaTeX puts more (vertical) space than desirable.
