I've noticed that XHTML comments that span multiple lines are deformed by po4a-translate. An additional empty line is inserted between every two lines: For example: <!-- Keep link lines at 72 characters or lynx will break them poorly. Obviously, we list ONLY the most useful/important URLs here. Keep it short and sweet: 3 lines and 2 columns is already enough --> Results to: <!-- Keep link lines at 72 characters or lynx will break them poorly. Obviously, we list ONLY the most useful/important URLs here. Keep it short and sweet: 3 lines and 2 columns is already enough --> This may be considered a cosmetic problem, but I've decided to report it anyway.
