Anchors are formatted by read/search as LINE+HASH|TEXT, and lines may be
prefixed with marker decoration (*, >, +, -). The parser previously required
a bare LINE+HASH and rejected verbatim copy-pasted anchors with:
line N: expected a full anchor such as "119sr", ...; got "364sp|".
Loosen LID_CAPTURE_RE to allow optional leading decoration and an optional
trailing |... body on each anchor (including each side of a range).
