Subject: Bug#159742: wdiff: --ignore-case option doesn't work,
     not properly documented (patch included)

Package: wdiff
Version: 0.5-12
Severity: normal

The command-line option --ignore-case (or -i) is supposed to cause wdiff
to do a case-insensitive comparison.  It doesn't work, at least when
diff 2.8.1-1 is installed.  Also, the option is not documented in the
wdiff manpage or in /usr/share/doc/wdiff (it is listed under wdiff
--help).

The following patch will fix wdiff to properly do case-insensitive
comparisons:
