Chris Reuter d26dbf036a Removed spaces from top-level directory names. 
Spaces tend to cause annoyances in a Unix-style shell environment.
This change fixes that.

/**
* Game of Combat
* <p>
* Based on the BASIC game of Combat here
* https://github.com/coding-horror/basic-computer-games/blob/main/28%20Combat/combat.bas
* <p>
* Note: The idea was to create a version of the 1970's BASIC game in Java, without introducing
* new features - no additional text, error checking, etc has been added.
*
* Converted from BASIC to Java by Darren Cardenas.
