Good quoting rquires to cut the quote down to the minimum. This means to edit the quote, not only on block-level, but also on line-level. E.g. I want to quote the first and last sentence of a paragraph, but not the sentence[s] in the middle, so I delete a lot and add a "[...]". Actual result: The blockquote is divided into two separate ones and "[...]" appears as new content. This is strictly correct, but awful and uncommon. Expected result: The "[...]" is added to the blockquote. Sometimes I also delete too much (including linebreaks) and readding it is faster than undo. Exactly this is the reason, why I use the plaintext editor in 4.x. I suggest to only break the blockquote, if I press return in it, otherwise just add, what I type, to it. But this doesn't help with inserting linebreaks in the quote. Any ideas?

reassign to joe for M16

this is an (extremely) simple change to make. It will go in as soon as I get my current large batch of changes ready to go in, which will definitely be M15.

by the way, if you want to just insert a break without splitting the quote, I believe using shift-return (or shift-enter, depending on how your keyboard names these things) will do what you want.
