Well -- the whole idea is to remove the rule targets.  I know of only
one use of multiple colons on a line -- in GNU make.  Even there,
everything before a ':' is a rule target.  My comment "limited to the
first ':'" may not be accurate, but I don't see any advantage to not
always removing everything before a ':'.
