Inaccurate note about color utils

[travisdahl]

The docs say:
Note that the .text-white and .text-muted class has no link styling.
but that isn't true, they still have link styling. Either the docs are wrong, or the functionality is wrong. If it's the docs, here is a PR. :)

Hovered over the muted link...

Hovered over the white link...

This is in reference to the fact that they do not use the text-emphasis-variant mixin, which adds a hover-color.

bootstrap/scss/utilities/_text.scss

Lines 42 to 49 in 8f7bd41

	.text-white { color: $white !important; }
	@each $color, $value in $theme-colors {
	@include text-emphasis-variant(".text-#{$color}", $value);
	}
	.text-body { color: $body-color !important; }
	.text-muted { color: $text-muted !important; }

@razh ah. I guess its just a bit unclear then. I consider the underline "link styling". You can close if its a non-issue
