Now, the `--width` option, although with a default value of 76, it's not set to any value initially so that the `--no-wrap` option can be passed without throwing an error. Fixes #145. With the above bug, another one was found where Babel was not mimic'ing xgtettext's behaviour regarding the `--no-wrap` option where comments are wrapped anyway to the width of 76, and, if `--width` is passed then that value is used to wrap the comments too.
