[notmuch] "From:" value containing ':'

[David Edmondson]

A message with a colon in the value of the 'From:' header will never be
shown by notmuch.el, as the regexp in notmuch-search-process-filter
allows any character in the author names except ':'. It's simple to
change the pattern, but I wonder what that will break.

Given that ';' is used as a delimiter, was the pattern supposed to
exclude ';'?
