Merge from 0.9.8.x branch, rel 245:
* S3/S3.py: Escape parameters in strings. Fixes sync to and
  ls of directories with spaces. (Thx Lubomir Rintel from Fedora Project)

You might try using the https://github.com/s3tools/s3cmd master branch and try reproducing the problem with that version. The testsuite within master branch syncs files with spaces in their names as part of standard testing practices, so this is known to work with recent code.
