- How should I ask for the first occurrence of N blank lines for some fixed,
yet large, N. I think emacs uses ^ for the start of the line, though I've
seen some regexp libraries (not for emacs) that use the ^ as a sort of
"exponentiation" symbol for the number of times a string is concatenated.


interactively: ^ C-q C-j \{ N \}

programmatically: "^\n\\{N\\}"


- How can I search for regexps that have one or more newlines in the middle?

interactively: \( .* C-q C-j \)*
programmatically: "\\(.*\n\\)*"
