In README point out that not all web pages can be properly saved to wallabag
I am not sure what the reason is, but I guess that it might have to do with javascript. It is probably not very useful to save a web page that can not be rendered in emacs. I am not bothered by this error, but it can trip up new users of wallabag.el: The first web page I tried out wallabag.el on had this problem.
If you use paw extension, the whole html will send to wallabag via paw-server, in that case, pages will be saved without pulling the url by wallabag server.
To clarify: I just think it would be a good idea to point out in the README that wallabag is about saving web pages that are mainly html-based, and some web pages that contain obfuscating javascript might not be possible to save usefully. Such a tip is just to help newcomers get up to speed, instead of leaving and thinking "I could not get it to work".
