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).

Best regards,
Tony.
