Exclude file list in tarsnaprc

[William Morris]

Hi

I am getting the hang of Tarsnap and would like to add 
a list of files and directories to exclude to .tarsnaprc.
However the list of excludes is not honoured.  I can add
the same entries to the command line and exclusion works.

Here is my current file:

        keyfile ~/.tarsnap.key
        cachedir ~/.tarsnap.cache/
        humanize-numbers
        nodump

        # Print statistics when creating or deleting archives
        print-stats

        # Create a checkpoint once per GB of uploaded data.
        checkpoint-bytes 1G

        exclude "Build/" 
        exclude "XCode/"
        exclude "local/"
        exclude "*~" 
        exclude "*.o" 
        exclude "*.DS_Store" 
        exclude "*.dSYM"

The file is definitely being processed (adding an invalid 
entry results in an error) but none of the exclusions works. 

I am using OS-X 10.9.3.

$ tarsnap --version
tarsnap 1.0.35

Thanks for your help
