Early Roguelike Collection: arogue5/chase.c annotate

annotate arogue5/chase.c @ 264:778938a5c21d

UltraRogue: add location for character files. When using the -n option, UltraRogue will look for character files in a single location, similar to save files. The location is chosen by defining CHRDIR in getplay.c, at least until UltraRogue gets integrated with the build systems.
