+-------------
+
+If the 'FLAGS' of a *point* or *url* rule contain the character `q`,
+then the rule's pattern will be matched against a copy of the input
+string where URL percent-escapes have been decoded so that, for
+example, the regular expression `^~` will match an input string that
+begins with either `~`, `%7E` or `%7e`.
+
+Even if such percent-escapes were decoded, however, the original
+version of the string will be used for any *restpat* expansion,
+regardlessly of whether the escapes were unquoted inside or outside
+the matched part of the string.
