Contrary to documentation:
The `-w' and `--ignore-all-space' options are stronger than `-b'.
They ignore difference even if one file has white space where the other
file has none. "White space" characters include tab, newline, vertical
--ignore-all-space does not make diff ignore newlines:
$ diff -u --ignore-all-space <(seq 3) <(seq 3|fmt)

Perhaps because diff is fundamentally line-oriented.
I haven't delved into this.
If you want that functionality, you might prefer wdiff.
