"s3cmd.rb get ..." returns 0 for Error 404

[andyuk]

Eg.
# s3cmd.rb get bucket:file/that/does/not/exist local.txt
S3 command failed:
get_stream file/that/does/not/exist  #<File:0xb7907588>
With result 404 Not Found

# echo $?
0

Since an error occured I would expect 1 to be returned.
Also local.txt is created, I don't think this should happen if the file does not exist.

I had to write a horrible hack in my bash script to work around the issue.
