some systems allow you to edit the command line without deleting
the characters that you pass over. Just back arrow to the "-"
and change to the "+" and press enter. Even MSDOS allowed this
if you were running DOSKEY. It was very handy back in my DOS-days.
Right now I am using POV-Ray for BeOS. No GUI for this port, so
everything is from a terminal and that command-line editing is
really handy.
