* Removed murky ' :' -> ' :' replacement in tokenizer. This breaks four parser tests, and should be fixed in a token stream transformer or DOM postprocessor. This replacement clashes with round-tripping, and is not terribly important visually. * Added stx:row annotation to single-line dt/dd pairs and use it to preserve single-line syntax in the serializer. There is no attempt yet to support the addition of nested lists in an originally single-line dd. We'd need to look ahead in the serializer to support this. Perhaps the editor can simply drop data-mw in that case. * Switched default dt/dd serialization to multi-line. This supports all nested lists and multiple dds. * Don't close dls when switching from dt to dd or back in the token stream ListHandler. Overall 290 round-trip tests are passing now (up from 284, some due to , some due to lists). The number of passing parser tests dropped slightly from 303 to 297 (or 301/295 on weekdays other than Thursday). Change-Id: I85ff40571833713388c6523e6a4ba2e94daa3807
