What about if those are missing? The third argument is the value when
the program could not be found, so I would think that using the
`missing' script would be appropriate here.

Please say `file name' (two words) instead of path, a path in GNU is a
search list, e.g. PATH, LD_LIBRARY_PATH, etc. I'd skip the (8) stuff,
we use info in GNU not man pages so those are kinda meaningless, if it
is important to point to the documentation we can use `(coreutils) id
invocation'. The docstring might even be simplified `netstat command'
or something.

Would it maybe be better to provide a wrapper around id instead? So
that `id -u' always works (or $ID). I'm thinking something along the
lines of,
id()
{
case $1 in
-u) if id_without_u_p; then
command id $1 | $SED -n 's,.*uid=\([0-9]*\).*,\1,p'
fi
break

command id -u
