- a hack in cmd_mkdir that was already obsolete a decade ago - to distinguish "echo" from "echo.", but that is the wrong way to implement this anyway. There's nothing particularly special about the period, "echo" is just one of those commands that is lenient about where its parameters begin, and when it echos a line, the first character (usually a space, but in the case of "echo." a period) is skipped. svn path=/trunk/; revision=35647
