Subject: Bug#648411: diffutils: description of -I option is wrong

Package: diffutils
Version: 1:3.0-1
Severity: normal

This is what the info page says:

    `-I REGEXP'
    `--ignore-matching-lines=REGEXP'
         Ignore changes that just insert or delete lines that match REGEXP.
         Uses grep systax.  See Specified Folding.

But the manpage says:

       -I RE  --ignore-matching-lines=RE
              Ignore changes whose lines all match RE.

which is misleading, because you cannot ignore things like (-I foo):

-foo: 1
+foo: 1
