Title: Added setlocal formatoptions-=c to disable automatically inserting bullets when auto-wrapping

Usually I have "set textwidth=80" for MarkDown files. It is annoying that vim keeps adding bullets on auto-wrapping and I believe this is not an expected behavior for most people. This change makes sure the behavior is prevented.
