process_backslash_command would drop the last character of the input command on the assumption that it was a newline. Given a non newline terminated input file, this could result in dropping the last character of the command. Fix that by doing an actual test that we're removing a newline. While at it, allow for Windows newlines (\r\n), and suppress multiple newlines if any. I do not think either of those cases really occur, since (a) we read script files in text mode and (b) the lexer stops when it hits a newline. But it's cheap enough and it provides a stronger guarantee about what the result string looks like. This is just cosmetic, I think, since the possibly-overly-chomped line was only used for display not for further processing. So it doesn't seem necessary to back-patch.
