When a line starting with '..' (anchor, comment, directive) is followed directly by a section underline without a blank line, the parser used to treat the whole markup line as the title text. It now skips title detection on explicit markup lines so the appropriate body rule (LinkRule, CommentRule, ...) can claim them, and the next paragraph becomes the section title. Closes phpDocumentor#1240
Hosts the helper next to its siblings (isLink, isDirective, isAnnotation), aligns its regex flags with the rest of the file, and exercises sub-section underlines, phrase-reference anchors and stacked anchors.

Closes #1240.
When an anchor (or any explicit markup line like a comment or directive) sits directly above a section underline without an intervening blank line, the parser used to greedily treat the markup line as the section title text. With this change,
TitleRule::applies()skips lines that start with..followed by whitespace (or a lonely..), so the body rules (e.g.LinkRule) can claim them and the next paragraph becomes the actual title, exactly as docutils does.Validated by a new integration fixture
anchor-no-blank-line/covering both single-space and double-space anchors directly above section titles.
