Implement smart formatting of comments

[hollasch]

I suppose that this is a backburner sort of item, but I really miss the smart formatting in Vim. For example, entering text in a // comment will not only wrap the line, but will also prepend the line with the appropriate comment syntax. It's also really handy when changing a paragraph comment, as you can use 'gqap' to reflow and recomment the entire paragraph.

Perhaps a limited solution (like gqap, or just insert-mode wrapping) is feasible.

Yeah it is nice to have that. I'll see if I can squeeze it into the next major release.

I'd like to second the request by @hollasch

gqap is something I use all the time, and something smarter than that for comments would be even better.

Thanks @jaredpar for this awesome plugin.

[jcredland]

This would be amazing.

The gq half of this request was implemented in PR #2274.

The other half of this request is the c, r and o options of formatoptions (see vim :help fo-table).

It turns out this is a duplicate of the older issue #573.
