Add region markers folding for Go

[c0m3tx]

Add region markers for folding Go code

// Region regionName

// EndRegion

[aeschli]

Is // Region already commonly used in Go? We typically use // #region

[c0m3tx]

@aeschli I tried to stay close to common Go syntax. # symbol is not used in the language AFAIK, but capitalized words are.

Also not inside a comment? the # avoids that comments starting with the word 'Region' trigger a (incomplete) folding range
@ramya-rao-a Can you advise?

Also not inside a comment?

@aeschli what do you mean?

I think that adding a foreign character in Go code may look strange, but if you think it would be better it's fine for me ofc 👍

[aeschli]

I'm just trying to understand, I'm a 'Go' novice. In the languages I know, comments can contain any character or symbol (maybe except for the comment end token). @ramya-rao-a is our Go expert. Let's wait for her input.

Ah ok I see! No, there is no issue with # characters in comments, they are totally fine.

[aeschli]

To be consistent with the other range markers, I updated the markers to // region, // endregion and // #region, // #endregion

Thank you @aeschli !
