Add remove_tag() function for add_tag() parallelism

[GoogleCodeExporter]

I've modified add_tag() to return a boolean indicating whether a tag was added 
and also added a 
parallel function for tag removal so that tags can be removed without modifying 
the other tags on 
the object.

Attached is a patch for those changes.

Apologies, there was a typo in the original diff.  Corrected patch below.

Thanks for the patch. Though it is rejected when I apply it (patch <
remove-tag.diff), it works fine when I copy-paste the code.

I wonder why there are no follow-ups to this issue. Is there another/a better 
way of
removing tags from objects? Or it has never occurred to anyone else to want to 
remove
a specific tag from an object?

A clarification from the maintainers would be very welcome.

Cheers

The lack of remove_tag struck me as quite strange too. Not difficult to work 
around
but an obvious addition.
