I was just reading this question: When "etc." is at the end of a phrase, do you place a period after it?
And it brought to mind something similar. If a phrase ends with a . (such as e.g. or etc.), and you want to use ..., how many periods should you put?
That is, which of these is correct?
something something etc...
something something etc....
To preempt the objection that ellipses never follow abbreviations, they can when used for aposiopesis in dialogue.
