Is there a document hosting service, allowing editing the documents using only Markdown or just raw text?Requirements:web 2.0 interface (quick saving with a shortcut, probably Ctrl-S; also auto-saving would be great), but lightweight (Google Docs is too slow and clunky for me here),permanent storage (not cookie-based or lost-on-leave), for free,multiple files per user, password protected (https would be a plus),optional: ability to view older revisions/versions of the text would be a plus.I've found two sites that looked very promising (for the rawtext option):http://www.simpletext.wshttp://writer.bighugelabs.combut both of them can't handle entering the  character of my native language (Polish), because they intercept AltGr+s keyboard shortcut as a shortcut to [S]ave file command. So that disqualifies them as for now.
