allow configuring the command line height using h,5EJ

* This allows for several customizations.
  * You can simply increase the visible command line history.
    For that you must also set SCI_SETWRAPMODE(SC_WRAP_CHAR).
    An example was added to fallback.teco_ini.
  * You could also set SCI_SETLINEENDTYPESALLOWED(SC_LINE_END_TYPE_DEFAULT)
    to see the structure of inserted text.
* Alternatively we could have introduced a new command like EP or FW
  and also overload it to replace the current ED&2048 (e.g. -EP and EP).
  In DEC TECO `W` comes closest to what 5EJ now does.
