The column is the position within the line after tab characters have been processed as 4-space tab stops.
If the line doesn't contain any tabs, it's the same as the {@link #getIndex()}. If the line starts with a tab,
followed by text, then the column for the first character of the text is 4 (the index is 1).
@return the current column within the line (0-based)
