bug#14114: tango-dark: background highlighting not working properly

[James Jong]

The following code does not work well on the builtin `tango-dark` theme:

    (custom-set-faces

     '(region ((t (:inherit nil :background "RoyalBlue4"))))

     '(highlight ((t (:inherit region :background "dark olive green"))))

     '(hl-line ((t (:inherit highlight)))))

Region highlighting works well and respects foreground faces:

but line highlighting doesn't:

There is a thread on StackOverflow discussing this:

Any thoughts?

Thanks,

James
