An explicit TL is that leading. Without one, Td does not set it: three or more rows at one repeated step stay one paragraph, and a single wider gap stays a break. A rewrite marks the whole paragraph, including a row it leaves in the source, so adding a row does not absorb the next paragraph on a later edit. When the paragraph is the last text on the page, that marker closes after the paragraph's last ET, so a kept source row stays inside it. When the next paragraph shares that text object, the marker opens after BT and closes before the neighbour's text. When the rewritten paragraph is the last one in that text object, the marker opens after the preceding paragraph and closes before the shared ET. The extra marker is not added when the paragraph is already one marked region and the next line is in a different region. Hyphenated line ends are joined. A row opening with a list marker starts its own item, and the row a list item wraps onto continues it at its hanging indent, so editing one item never takes the items after it. Still open: a larger heading joined to smaller body lines (#1756) and cells in different columns (#1680, #2478). Two rows and no third step still cannot be told from a paragraph break when there is no TL."
