A literal backslash needs to be doubled so that the parser doesn't treat it as escaping the following character when the markdown is read back. In ca4774131b9b8ee40b4d7f5c1ba296af4700207f we tried to limit it to backslashes that were not already escaped. In case someone really needs a longer series of backslashes, it's more correct to escape them all; but this comes with the risk that if they do not get un-escaped by the markdown parser in some scenario, repeated round-trip saving and loading could multiply them excessively. So we also add a lot of tests to try to verify that this is safe.
