EOL error on Windows and CRLF with SASS mixins

[Storm203]

When using CSSComb on a SASS file that has multiple includes in a single selector, in a file on Windows that is using CRLF for EOL, the indenting gets all buggy:

Before CSSComb:

#created_by_container{
    @include display-flex;
    @include flex-direction(column);
    @include justify-content(center);
    @include align-items(center);
}

After CSSComb:

#created_by_container{
    @include display-flex;

@include flex-direction(column);

@include justify-content(center);

@include align-items(center);
}

This does not occur when using LF only, however there is no git option to check out CRLF as LF and then commit back as CRLF (only the reverse exists).

Possibly the same issue as #592
