Multiple cachedirs by specifing the -c option more than ones.

Also other minor changes: - Removed leading whitespaces in parse_filename() - Aligned --nocolor with other long options in usage()

NAK. You should have just left this alone. There's no concept of localizing variables to functions except to declare them as function parameters, so in order to distinguish the "required" parameters from the localized variables in the function, the convention is to add some whitespace in the parameter list. Don't worry about this -- I'm pulling your patch to my local with this change reverted (and fixing up the commit message). Thanks!
