it seems to be a bug in r.colors, the attached patch quickly fix it.
Anyway r.colors needs some more cleaning. In GRASS7 I would suggest to

-i   Enter rules interactively

1) then if rules file is given read from the file
2) if not given (and color=rules) switch to the interactive mode
3) or completely remove interactive mode, print error about missing
rules file <- seems to be a better solution, to avoid any interactive
mode in GRASS7
