Diagnostics are not shown if the start and end character offset are the same

[nadeeshaan]

Description: Consider the following scenario,

function test() returns {
}

In the above, I have a diagnostics at the start of the {. For example, my params look as below,

{
   "start":{
      "line":0,
      "character":25
   },
   "end":{
      "line":0,
      "character":25
   }
}

But it has no sense, hasn't it?.. You can't highlight range with 0 length.

@nixel2007 I was thinking if we can provide the same behaviour as in VSCode since VSCode properly provides the diagnostic in this scenario.

@nadeeshaan could you share a screenshot from vscode with zero-length diagnostic?

Hm. Interesting. Looks like vscode adds some "virtual" space char for highlighting
