Add after-dollar-variable option for dollar-variable-empty-line-before ignore

[qmhc]

I want to group variables of different types, like following:

$vxp-color-primary: #339af0;
$vxp-color-info: #3bc9db;

$vxp-border-radius; 4px;
$vxp-border-radius-large: 6px;

But ignore options of dollar-variable-empty-line-before rule not support after-dollar-variable.

When I added after-dollar-variable to except options, the following gets error:

$vxp-color-info: #3bc9db;

$vxp-border-radius; 4px;

Or I removed after-dollar-variable from except options, the following gets error:

$vxp-color-primary: #339af0;
$vxp-color-info: #3bc9db;
