Mozilla, Konqueror, Konsole can have several sessions open simultaneously as
"tabs" in one window. For KDE Konsole, a tab is one window shell or shell
session.

See gplt_x11.c:

static char*
getMultiTabConsoleSwitchCommand(unsigned long *newGnuplotXID)

which says:

 * Currently implemented for:
 *	- KDE's Konsole.
...
 /* now test for GNOME multitab console */
 /* ... if somebody bothers to implement it ... */
...


What it does:
1. Konsole session 1: run gnuplot, "plot x"
2. Open/switch to another session
3. Hit "Space" in gnuplot's X11 => gnuplot sends focus to the correct
konsole and browses it to the appropriate session

I think that GNOME has also multitab consoles -- that could be useful if
someones adds the same functionality there.

That's the correct fix, I've just cvs'ed it.
