[cssparser-developers] TAB handling

Hi,

I wondered why the columnNumbers for characters following a TAB 
character are so big. The TAB character seems to be treated like 8 
characters. I found the following:

com.steadystate.css.parser.ASCII_CharStream.UpdateLineColumn(char c), 
line 162:

         case '\t' :
             this.column--;
             this.column += (8 - (this.column & 07));
             break;

Why is this special treatment for TAB?
