* 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
