Actually I was first trying to directly look at function argument count as you
mentioned, but unfortunately Symbols coming from index don't have any
declarations. Therefore it turns back to looking at Signature in this case,
which is same with this one. Apart from that, IIUC, SnippetSuffix contains
anything only when completion item is a function otherwise it is empty. So IMO
this check should be OK.
