There should be an option to ignore leading white space, like
there is one for trailing white space, and it should probably
be integrated in the -b option.

Basically, I'd like to be able to get only lines that differ by words.

Currently:

cventin:~> diff -bu <(printf "ab cd\n") <(printf " ab  cd \n")

-ab cd
