wdiff -i broken?

[Ben Armstrong]

wdiff -i (--ignore-case) doesn't work, so far as I can see.

address@hidden:~$ cat foo
foo
Bar
quux
address@hidden:~$ cat bar
Foo
bar
baz
address@hidden:~$ wdiff foo bar
[-foo
Bar
quux-]{+Foo
bar
baz+}
address@hidden:~$ wdiff -i foo bar
Foo
bar
baz

Huh?  I just get a copy of my "bar" test-file output.

address@hidden:~$ wdiff --version
GNU wdiff 0.5
Copyright (C) 1992 Free Software Foundation, Inc.
address@hidden:~$ diff --version
diff - GNU diffutils version 2.7

I have reproduced the problem on a Debian "woody" system and on a w32/cygwin
system.

Thanks,
Ben
