Re: [PATCH] Use completing-read-multiple for org-set-tags-command

[Clemens]

Sorry, I just figured out you get indeed completion after the first tag 
my sandbox wasn't clean (usually that shouldn't affect the completion 
behavior but somehow it did, I have to check why). In this case your are 
also right that `org-tags-completion-function` need to be adjusted. My 
patch still is useful to make frameworks which support 
`completing-read-multiple` automatically work though while the current 
approach is tightly integrated with the default completion.

I will do some more work and report back.
