Subject: [PATCH] _tar: improve completion of long options
Date: Wed, 18 Sep 2019 18:34:57 +0900
Message-ID: <BA72AA66-3FA4-4A39-B77F-F84457A2F8BA@kba.biglobe.ne.jp> (raw)

_tar does not complete long options in many cases, for example:

tar t --<TAB>
tar tf a.tar --<TAB>
tar -t -f a.tar --<TAR>

In the following workaround, the spec '*: : true' tells _arguments that
't', 'tf' or 'a.tar' in the examples above are legal and do not stop
completion at these "arguments".
The effect of '-f+:' is not to complete long options for
tar -f --<TAB>
