Minor cosmetic tweaks to expand. Working my way through the to-review list that predates the "pending" directory. This gets expand off my to-review list. (Proof that "need to review" doesn't mean it's in bad shape, this command was fine. Changed capitalization in the help text because I'm trying to have "user supplies this value" be all caps, switched a read() to readall() although I'm not sure modern kernels actually allow -EINTR to generate zero length reads anymore, and since most of the loopfiles() target functions are called do_commandname() changed the name to that just so it's regular. None of the changes are actually important. :)
