If the interspersed option is set false and one arg is already set all
following arguments are counted as arg and not parsed as flags. Because
of that we should not offer flag completion. The same applies to arguments
followed after `--`.

* Bash completion v2
This v2 version of bash completion is based on Go completions.
It also supports descriptions like the other shells.

When handling ShellCompDirectiveNoSpace we must still properly handle
descriptions. To do so we cannot simply use 'compadd', but must use
zsh's '_describe' function.
Also, when handling ShellCompDirectiveNoSpace we cannot assume that
only a single completion will be given to the script. In fact,
ValidArgsFunction can return multiple completions, even if they don't
match the 'toComplete' argument prefix. Therefore, we cannot use the
number of completions received in the completion script to determine
if we should activate the "no space" directive. Instead, we can leave
it all to the '_describe' function.
Fixes#1212
When handling ShellCompDirectiveNoFileComp we cannot base ourself on
the script receiving no valid completion. In fact,
ValidArgsFunction can return multiple completions, even if they don't
match the 'toComplete' argument prefix at all. Therefore, we cannot use
the number of completions received by the completion script to determine
if we should activate the "no file comp" directive. Instead, we can
check if the '_describe' function has found any completions.
Finally, it is important for the script to return the return code of the
called zsh functions (_describe, _arguments). This tells zsh if
completions were found or not, which if not, will trigger different
matching attempts, such as matching what the user typed with the the
content of possible completions (instead of just as the prefix).

Flag definitions like `-asd` are not handled correctly by
the custom completion logic. They should be treated as
multiple flags. For details refer to #1257.

Make it easier for programs to provide shell completion by creating
the 'completion' command automatically.
If a 'completion' command is already provided by the program, Cobra
will use that one instead.
