[folding] Allow folding block comment that starts in the middle of the line

[mhermher]

An additional request on top of now-closed feature-request 11524.

I sometimes like to write my block comments in this form:

let someflag : boolean = false;/*
    this flag does blah blah
    blah blah blah blah*/
let somethingelse : string;

So that folding that comment completely removes it from view outside of that trailing start marker. However, the implementation to feature-request 11524 does not detect this type of block comment and only seems to pick up on block comments started on their own new line. I am not sure how popular that style of commenting is, but it would help me a lot of it could be picked up by that feature.

Thanks.

Hm, difficult with what we have:

• we support only folding whole lines, not parts of it
• our folding is based on indentation only. To do more than that we require language aware folding: [folding] language-aware folding #3422

Hi Martin. Thanks for the reply. Sorry about the markup in my example, but lines 2 and 3 above should be indented, but they didn't come out right in the GitHub comment editor thing. If indented properly, the code does actually fold if you click the +/- markers in the left margin. My issue was specifically with the auto-folding for comments feature (cmd K cmd /), which does not pick up this kind of commenting.

I fixed your comment (using the triple backtick).

Ok, I see, I guess for this case we could make 'fold comment' work.
