Since "--files-from" is a prefix of "--files-from0", getopt would
recognize "--files-from" as an alias for "--files-from0".  That's
confusing.

One workaround for this problem would be to add --files-from as a
separate (undocumented) option that always reports an error.

Another possibility is to require that --null also be specified if
--files-from is specified.

Another thought: perhaps "--files0-from" would be a better name for
the combined option?  After all, the NULs immediately follow the file
names, not the place where the file names come from.
