Apart from removing the \\ that elisp requires, I copied it from the
Emacs info node on regular expressions. Although I see now I should also
have removed the \ before the double quote. If you break it down into
pieces:

[.?!]   period, question or exclamation mark followed by
[]"')]* any number of closing brackets or quotes

You can use a literal ] in a list without escaping if it's the first
character in the list.
