df: work around long-named /dev/disk/by-uuid/... symlinks
On systems with recent kernel/tools, a symlink from /etc/mtab to
/proc/mounts, and a by-UUID mount (i.e., soon, nearly everyone),
you will see something like the following when running "df -hT":
(this has been truncated to fit in a width-limited ChangeLog file)
When that long /dev/disk/by-uuid/... name is merely a symlink
to a much shorter (and often more useful) device name like
"/dev/sda3", and when it's part of a listing of all file systems,
I would much prefer to see only the latter. Similarly, when using
an encrypted root file system, you would see a name like
/dev/mapper/luks-828fc648-9f30-43d8-a0b1-f7196a2edb66 pointing
to say, /dev/dm-0, I prefer the shorter name.
I.e., if I explicitly run
"df -hT /dev/disk/by-uuid/828fc648-9f30-43d8-a0b1-f7096a2edb66",
then, it's fine -- and expected -- to print to the long name.
It was explicitly given. However, with no non-option argument,
df should print the shorter name. Note that performing this

would make it impossible to distinguish those two cases.

sort: clarify wording on -k syntax
* src/sort.c (usage): Use KEYDEF instead of POS, and call out the
specific OPTS that can occur in KEYDEF.

id: fix bug when euid != ruid
* src/id.c (main): Report an error if no args are given and getuid
fails, because print_full_info needs ruid. Redo code so that
getuid and friends are invoked only when needed; this makes the
code easier to follow, and is how I found the above bug.

ls: another reword of generic size note
* src/system.h (emit_size_note): Use "unit" rather than "suffix",
and move multiplication to example instead of in suffix list.
