Suppressing Differences in Blank Lines
The '-B' and '--ignore-blank-lines' options ignore insertions or deletions of blank lines. These options normally affect only lines that are completely empty; they do not affect lines that look empty but contain space or tab characters. With these options, for instance, consider a file containing only the following.
1. A point is that which has
no part.
2. A line is breadthless length.
-- Euclid, The Elements, I
The last example is considered identical to another file containing only the following.
1. A point is that which has
no part.
2. A line is breadthless length.
-- Euclid, The Elements, I
