-----------------------------------
bq. Why we need this ( ), we can have just * right?
It was not intentional, that was the natural choice for me, but you are right
it works well without the ()s. I am uploading the new patch (A rebased one to
get all the unit test fixes)

> As of now s3g can't be used with s3cmd (which is seems to be an other popular
> s3 cli) as it doesn't add any space to the authorization headers.
> Example command:
> ```
> s3cmd ls --no-ssl --host localhost:9878 --host-bucket
> '%(bucket)s.localhost:9878' s3://b1qwe
> ```
> Result:
> {code}
> ERROR: S3 error: 404 (AuthorizationHeaderMalformed): The authorization header
> you provided is invalid.
> {code}
> With the debug option the header could be checked:
> {code}
> DEBUG: Processing request, please wait...

> The problem here is that we have no spaces between the segments of the
> authorization headers but we expect them in the AuthorizationHeaderV4 class.
