+		Adds a List of autocmds and autocmd groups.

+autocmd_get([{opts}])					*autocmd_get()*
+		Returns a |List| of autocmds. If {opts} is not supplied, then
+		returns the autocmds for all the events in all the groups.
+
+		The optional {opts} Dict argument supports the following
+		items:
+		    group	Autocmd group name. If specified, returns only
+				the autocmds defined in this group. If the
+				specified group doesn't exist, results in an
+				error message.  If set to an empty string,
+				then the default autocmd group is used.
+		    event	Autocmd event name. If specified, returns only
+				the autocmds defined for this event.  If set
+				to "*", then returns autocmds for all the
+				events.  If the specified event doesn't exist,
+				results in an error message.
+		    pattern	Autocmd pattern. If specified, returns only
+				the autocmds defined for this pattern.
+		A combination of the above three times can be supplied in
+		{opts}.
+
+		Each Dict in the returned List contains the following items:
+		    bufnr	For buffer-local autocmds, buffer number where
+				the autocmd is defined.
+		    cmd		Command executed for this autocmd.
+		    event	Autocmd event name.
+		    group	Autocmd group name.
+		    nested	Set to v:true for a nested autocmd. See
+				|autocmd-nested|.
+		    once	Set to v:true, if the autocmd will be executed
+				only once. See |autocmd-once|.
+		    pattern	Autocmd pattern.  For a buffer-local
+				autocmd, this will be of the form "<buffer=n>".
+		If there are multiple commands for an autocmd event in a
+		group, then separate items are returned for each command.
+
+		Examples: >
+			" :autocmd MyGroup
+			echo autocmd_get(#{group: 'Mygroup'})
