Bug#1013918: lintian: False positive: `chown --reference=foo bar.baz` triggers chown-with-dot

[Guilhem Moulin <guilhem@debian.org>]

Package: lintian
Version: 2.115.1
Severity: normal

Dear Maintainer,

roundcube-core's postinst contains

    chown --reference="$CONFFILE" "$CONFFILE.ucftmp"

which triggers a false positive with tag chown-with-dot.  Indeed
"chown --reference=foo bar.baz" matches

    m{ \b chown \s+ (?: -\S+ \s+ )* ( \S+ [.] \S+ ) \b }x,

but that chown command has no ambiguous user.group argument.

Thanks for maintaining Lintian!
