Subject: Use a single enumerated type, Verbosity, instead of
X-Git-Tag: FILEUTILS-3_16j~9
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e375f4e9c89d30c7823ce715dbc4f008669b7df3;p=thirdparty%2Fcoreutils.git

Use a single enumerated type, Verbosity, instead of
the two booleans, verbose and changes_only.  This fixes a bug whereby
--change had the same effect as --verbose.
