+ * 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
+ * non-NULL pointers.
