[bug]: set of token cases

[Shuraken007]

Describe the bug

Hello, I'm trying to make theme like visual studio code have (default dark theme).
So, I founded some strange cases, or absence of some expected things.

bugs

1. third hyphen option affects following string argument with blue color (33), I can't found how to redefine this
   
2. more strange things with arguments
   
3. second argument have default white color
   
4. path after source command is blue (33), while I defined section [paths] with orange 173
   

[paths]
path          = 173
pathseparator = 
path-to-dir   = 173,underline
globbing      = 173,bold

5. backward slash breaks variable parsing
   
6. array variable buffer not recognized at this case
   
7. builtin have higher priority than subcommand, does it expected? looks less readable for me
   

absence of expected things

1. it's not possible to make different colors for left / right parts of assign statement
   
2. not possible to have custom colors for some special keywords
   

Where token parsing rules are located? Probably I'll fix smth.

Also last not important question / feature request.
Does it possible to define my custom colors at ini?
it's not handy to use numbers, better define colors with some name
