Note that empty lines and lines consisting solely of literal tabs and spaces will be ignored for the purposes of determining indentation, but escaped tabs and spaces are considered non-indentation characters. +For the purpose of measuring an indentation, a horizontal tab is regarded as a +sequence of one to eight spaces such that the column position corresponding to +its end is a multiple of eight.
