LogLevel VERBOSE only tells you what line number is matched. That is
not much use if authorized_keys changes over time (it does for me)
and ssh sessions could be up for days. I think it will also log
key fingerprints, but I don't know how one can obviously associate
them with a particular matched line (especially if your authorized_key
file contains the same key on multiple lines with different from=
match blocks).
