           Summary: Improve tooltip text and layout

           Version: D2
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: enhancement
          Priority: P1

from https://forum.dlang.org/thread/imrhiouthncheeekksny@forum.dlang.org:

* Tooltips on token-string literals adds a lot of extra spacing between
symbols.

* Tooltips that show documentation can have excessive line breaks.

* Tooltips on variables repeat attributes - eg, "private int length;" produces
"private private(int) [parent].length" instead of perhaps "(variable) private
int [parent].length".

* C#-style formatting and colourisation in tooltips.
