#711 Use COLOR FC only in error state

[SPE Anatol]

I have noticed the following way of notifying the user of a command line tool error under Microsoft Windows:

COLOR FC
PAUSE

That is a very good idea; however, if the console window is to be reused, it should rather be

COLOR FC
PAUSE
COLOR

because the error color remains after the user has acknowledged the error, meaning that following errors cannot signal with such alarm colors any more.
