Rename files in batch

Replace underscores with spaces in filenames and dirnames, recursively into subdirs.
Everyone wants to take spaces out of filenames. Forget that. I want to put them back in. We've got tools and filesystems that support spaces, they look better, so I'm going to use them. Because of how find works I find I need to run this multiple times, if it's renaming subdirs. But it can be re-run without issues. I got this version of the command from a comment in this underscore-generating command. http://www.commandlinefu.com/commands/view/760/find-recursively-from-current-directory-down-files-and-directories-whose-names-contain-single-or-multiple-whitespaces-and-replace-each-such-occurrence-with-a-single-underscore. All I did was change the regex.
