      I'm surprised that there has been no reply yet to this post.

      To check if auto commands exist for a given group, I can imagine two
      possibilities; you will have to experiment to see what works:

      a) see ":help exists()" [near the end of the list]. I'm not sure this
      allows you to test if autocommands are defined for a given group if you
      don't know which patterns or events are possible in that group.

      b) see ":help autocmd-list" and ":help :redir". Finding out that you got
      an empty list may be tedious. Also the title may depend on your messages
      language (see :help v:lang and what it resends to).

      that's my point.
