Exit value for "s3cmd ls"

[victor73]

$ s3cmd ls s3://path/to/non-existent/object

returns 0. This means that s3cmd ls cannot be used to check if a particular object exists in a bucket or not.

https://github.com/mdomsch/s3cmd/tree/bug/exitcodes
has a stab at adding proper exit codes to s3cmd. This attempts to address bug #19, #65, and #219 from a systematic POV.

If you hate using s3cmd because is almost always returned exit code 0 regardless, please take a look at this (short) branch and comment.

Thanks,
