Keyboard input losses also on MS Windows

[Hans-Bernhard B. <br...@ph...>]

One further problem I just discovered after a problem report by Dietmar 
Warning:  wgnuplot now tends to lose the first keypress after starting
the program.  This did not happen with 4.0.0, and is fixed by back-dating
mouse.[ch] and readline.c to that state.  Which rather strongly hints at
problems with the mousing/keyboard synchronization not only on X11, but
also on MS Windows.

Dietmar's original problem is vaguely similar, but harder to reproduce:
flipping open the menu of the text window, click on the title bar of the
text window, then type something.  Sometimes the first keypress will be
ignored.  But backdating those files to 4.0.0 doesn't cure this problem 
--- it doesn't seem to occur in 4.0.0 though.
