1417   "Used by `mdw-line-prefix' and `mdw-fill-paragraph'.
1418 If there's no fill prefix currently set (by the `fill-prefix'
1419 variable) and there's a match from one of the regexps here, it
1420 gets used to set the fill-prefix for the current operation.
1421
1422 The variable is a list of items of the form `PATTERN . PREFIX'; if
1423 the PATTERN matches, the PREFIX is used to set the fill prefix.
1424
1425 A PATTERN is one of the following.
1426
1427   * STRING -- a regular expression, expected to match at point
1428   * (eval . FORM) -- a Lisp form which must evaluate non-nil
1429   * (if COND CONSEQ-PAT ALT-PAT) -- if COND evaluates non-nil, must match
1430     CONSEQ-PAT; otherwise must match ALT-PAT
1431   * (and PATTERN ...) -- must match all of the PATTERNs
1432   * (or PATTERN ...) -- must match at least one PATTERN
1433   * (not PATTERN) -- mustn't match (probably not useful)
1434
1435 A PREFIX is a list of the following kinds of things:
1436
1437   * STRING -- insert a literal string
1438   * (match . N) -- insert the thing matched by bracketed subexpression N
1439   * (pad . N) -- a string of whitespace the same width as subexpression N
1440   * (expr . FORM) -- the result of evaluating FORM
1441
