Disk space (was: SELF: Anatomy of an (alleged) failure)

There are two separate binaries because the GNU Project thinks it is confusing to have single binaries whose behaviour changes depending on what name they are run as, even though this is ancient hoary Unix tradition. Apparently people might go renaming the binaries and then get confused when they don't work the same. Because we do that all the time, y'know.

(I think this rule makes more sense on non-GNU platforms, where it is common to rename *everything* via --program-prefix=g or something similar, to prevent conflicts with the native tools. But why should those of us using the GNU toolchain everywhere be penalized for this?)
