Once you are root it is too late, AFAICT. We anticipate that the
effective user ID is:

# id -u
0

But the real user ID is the same:

# id -ur
0

I.e. we _really_ are root. It's the same for sudo, so it appears that
the test is only useful in the case of setuid.

Without a means of differentiation, the simplest fallback seems be to
"su -p" (i.e. --preserve-environment) That preserves all your little
aliases and fiddles, e.g.:

$ which ll
ll is aliased to `ls -alF'

$ su -p
Password:
root@ratatosk:~# which ll
ll is aliased to `ls -alF

So aliasing vim to use an explicitly nominated .vimrc would also be
respected. (Preservation confirmed only on ubuntu, as I gave up on RH
more than a decade ago, and stopping to arc up the debian lappy won't
add much. :)

P.S. OK, yes, because the "type" command is the worst named in the unix
pantheon, I've used this for more than a quarter of a century:

$ which which
which is aliased to `type -a'

So please substitute "type" for "which", above, if wishing to replicate
the test without the sanitising alias.
