Thanks for the report. It looks like two issues. The main one is that
"notmuch config list" is not sanitizing the input sufficiently, so if
extra ';' are added, they show in the list output. The second is that
notmuch setup is adding ; to single item lists.

PS. For better or worse, HTML is bound to get mangled this list.
