bug#74785: 27.1; Fill-paragraph in RST mode does not respect line blocks

Not in my test, no.  With a paragraph like:

    | bblblbl
    | asdfasdf
    | asdasdf

M-: (and (looking-at adaptive-fill-regexp) (match-string 0)) RET
returns a string that contains only the leading spaces.

`paragraph-start` doesn't match those lines either.
