tar completion fails on tar files with colon in names

[Mikhail Gusarov <misha@xxxxxxxx>]

Hello.

GNU tar has a "feature" where it treats tar filenames with colons in it as files on remote filesystems:

% tar tf x:foo
tar: Cannot connect to x: resolve failed

%

It has an option to disable this "helpful" behaviour:

% tar --force-local -tf x:foo  
xx

%

However zsh completion for tar does not take it into account:

% zsh -f
% autoload -U compinit
% compinit
% tar --force-local -tf x:foo <TAB>tar: Cannot connect to x: resolve failed

Best,

Misha.
