gq incorrectly handles triple-slash doc-comments

[rnewman]

Steps

Type a line like the following, in Rust:

/// One two three four five six seven eight nine ten. One two three four five six seven eight nine ten. One two three four five six seven eight nine ten.

Visually select the entire line: 0v$

Reformat line: gq.

Expected:

With 100-column wrap:

/// One two three four five six seven eight nine ten. One two three four five six seven eight nine
/// ten. One two three four five six seven eight nine ten.

Actual:

With 100-column wrap:

// / One two three four five six seven eight nine ten. One two three four five six seven eight nine
// ten. One two three four five six seven eight nine ten.

Technical details:

• VSCode Version: 1.11.0-insider
• VsCodeVim Version: 0.6.11
• OS: macOS 10.11.6.

This might be an incredibly easy bug for anyone who wants to contribute to pick up.

(or it could be incredibly hard...)

Hmm, I'm not sure this is actually fixed? The initial problem is, but now the first of the resulting wrapped lines is indented one space too few:

    /// Mark this node as sharded by a value that stems from the given column of the given source awdkjd

after Vgq turns into

   /// Mark this node as sharded by a value that stems from the given
    /// column of the given source awdkjd

Yeah I realized I fucked it up in #1684. I fixed the bug in a pr, but there's a couple more gq related bugs I want to fix (plus it's finals week for me, so I haven't had too much time).
