    mime.c: Do not match a trailing period
    
    Do not include a trailing period ('.') when matching an URL.
    Most often it's end-of-sentence punctuation rather than part of
    the URL. See the thread at
    <URL:https://mail.gnome.org/archives/balsa-list/2018-July/msg00000.html>.
    
    * libbalsa/mime.c (get_url_reg): do not match a trailing period.
