Description:

python2-magic should be an optional dependency to s3cmd, since it's used to determine the mimetype based on contents (instead of simply the file extension).

It should NOT be listed as a dependency, since s3cmd performs all the duties (but trying to guess the mimetime based on contents) without it.

This information is provided directly by s3cmd, when performing an upload without this package installed:

WARNING: Module python-magic is not available. Guessing MIME types based on file extensions.

(note: "python-magic" is the python package name. This module is provided by the "python2-magic" Arch Package

Additional info:
* package version(s): 1.6.1-1 (latest, at the time)
* config and/or log files etc.


Steps to reproduce:

- install the s3cmd package, and take notice of the optional packages.
- note that python2-magic is absent
- try and perform a file upload to S3 with a mislabeled extension (example given was a .box Vagrant file)
- note the message provided by s3cmd, referring to the fact that since this module is unavailable, it will only take into account the file extension
- on S3 after the upload completes, note that the mimetype is wrong
