+ * m_functions execute protocol messages on this server:
+ *
+ *    cptr    is always NON-NULL, pointing to a *LOCAL* client
+ *            structure (with an open socket connected!). This
+ *            identifies the physical socket where the message
+ *            originated (or which caused the m_function to be
+ *            executed--some m_functions may call others...).
+ *
+ *    sptr    is the source of the message, defined by the
+ *            prefix part of the message if present. If not
+ *            or prefix not found, then sptr==cptr.
+ *
+ *            (!IsServer(cptr)) => (cptr == sptr), because
+ *            prefixes are taken *only* from servers...
+ *
+ *            (IsServer(cptr))
+ *                    (sptr == cptr) => the message didn't
+ *                    have the prefix.
+ *
+ *                    (sptr != cptr && IsServer(sptr) means
+ *                    the prefix specified servername. (?)
+ *
+ *                    (sptr != cptr && !IsServer(sptr) means
+ *                    that message originated from a remote
+ *                    user (not local).
+ *
+ *            combining
+ *
+ *            (!IsServer(sptr)) means that, sptr can safely
+ *            taken as defining the target structure of the
+ *            message in this server.
+ *
+ *    *Always* true (if 'parse' and others are working correct):
+ *
+ *    1)      sptr->from == cptr  (note: cptr->from == cptr)
+ *
+ *    2)      MyConnect(sptr) <=> sptr == cptr (e.g. sptr
+ *            *cannot* be a local connection, unless it's
+ *            actually cptr!). [MyConnect(x) should probably
+ *            be defined as (x == x->from) --msa ]
+ *
+ *    parc    number of variable parameter strings (if zero,
+ *            parv is allowed to be NULL)
+ *
+ *    parv    a NULL terminated list of parameter pointers,
+ *
+ *                    parv[0], sender (prefix string), if not present
+ *                            this points to an empty string.
+ *                    parv[1]...parv[parc-1]
+ *                            pointers to additional parameters
+ *                    parv[parc] == NULL, *always*
+ *
+ *            note:   it is guaranteed that parv[0]..parv[parc-1] are all
