Count unhidden lines from hide-lines?
I want to count the number of lines shown with hide-lines-matching.
count-lines seems to return the wrong number.
(length hide-lines-invisible-areas) seems to be related in that we hide the regions between the lines.

How to get line number for a given buffer position in a performant way?
I have list of buffer positions and I want to get the numbers of the lines at those positions. Is there a better way to do that then using with-current-buffer, goto-point and get-thing-at-point 'line? I want the code to be as fast as possible.

Is arbitrary buffer position at the beginning of a line?
What's the simplest way to check whether a given point value p is at the beginning of some line or not? Is there anything simpler than (save-excursion (goto-char p) (= p (point-at-bol))) or (member (char-before p) '(nil \n))?
