It's nice when there's no file extension.  If you're just using S3 for media, that's probably an unlikely scenario, but if you're mirroring your whole website, it may come up once or twice.  I know I've got some text files, like README, that fall under this.

Apache has a similar setting, which is set to text/plain, IIRC.  I think not setting any Content-Type is bad practice.

Hi all,

Here's a patch against 1.2.3 that adds a --default-mime-type (-t) option.  This MIME type is used if it's not in the MIME types file (S3SYNC_MIME_TYPES_FILE).  Two common values for this would be text/plain and application/octet-stream.
