For gvim, the X works as expected but what would be a more expected convention from exiting a cl text editor be? Most long running cli tools people are used to are read only and have just a few keys for different views and they tend to use 'q' or 'Esc', any single key isn't an option for a text editor. If they're in normal mode, Ctrl-c does give the message "Type :quit<Enter> to exit Vim" but I'm guessing most people don't notice it or think the ':' isn't part of the what they have to type because they don't now commands start with it, I would change it to "Type ':q<Enter>' to exit Vim". But people tend to accidentally leave normal mode by trying to type other things, so the Ctrl-C message isn't always helpful.
