Subject: bug#72274: option to ignore leading white space

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")
--- /proc/self/fd/11    2024-07-24 13:58:43.515131625 +0200
+++ /proc/self/fd/14    2024-07-24 13:58:43.515131625 +0200
@@ -1 +1 @@
-ab cd
+ ab  cd
