Godot-proposals: Line index color of empty lines should be white

[MaaaxiKing]

Describe the project you are working on:

Describe the problem or limitation you are having in your project:
Empty lines aren't unsafe lines but they aren't real safe lines, they're just empty. The line index color is sometimes green (safe) and sometimes gray (unsafe). I couldn't find what it depends on.
Describe the feature / enhancement and how it helps to overcome the problem or limitation:
Empty lines/ lines with spaces/ lines with indentations should have the line index color white.
Describe how your proposal will work, with code, pseudocode, mockups, and/or diagrams:
1 extends Node
2
3 var test
If this enhancement will not be used often, can it be worked around with a few lines of script?:
No.
Is there a reason why this should be core and not an add-on in the asset library?:
_I don't have experience with add-ons._

Empty lines aren't unsafe lines but they aren't really safe lines

In fact, empty lines are the safest lines. :laughing:
Three colors is too much. Gray color indicates possible type errors. If there are no such errors, then all lines should be green.

tbh this sounds more like a bug.

[MaaaxiKing]

@KoBeWi Yes, I also think it's a bug but I made a proposal because I don't want this bug to be fixed and then the color would be changed anyway to another (my suggestion: white) if this proposal will be accepted.

Having three different line number colors might start looking like Christmas :slightly_smiling_face:

I think it'd be better to always mark blank/comment lines as safe instead.
