_arguments -C … && ret=0 or _arguments -C … && return 0

[Nikolai Weibull <now@xxxxxxxx>]

Hi!

What’s the preferred way of dealing with _arguments calls that may use actions?

Etc/completion-style-guide suggests using _arguments -C … && return 0,
but many completion definitions use _arguments -C … && ret=0.

For example, Completion/Unix/Command/_bzip2 uses the_arguments -C … &&
ret=0 style.  This leads to files matching -* being included as
completions.  Is this desired behavior, or is it simply a bug?

Current behavior:

% touch ./--hello
% bzip2 --h^I
[option]
--help               display help message
[file to compress]
--hello

For most commands, completing a file name that looks like an option
will result in an error, so my gut feeling is that we should return
instead of looking for the additional possible completions.
