If that's the code fragment you were referring to, then the
explanation why it is disabled but left in the sources is right there
in the comment, viz:

   This is the old version of expand-file-name, before it was thoroughly
   rewritten for Emacs 10.31.  We leave this version here commented-out,
   because the code is very complex and likely to have subtle bugs.  If
   bugs _are_ found, it might be of interest to look at the old code and
   see what did it do in the relevant situation.

   Don't remove this code: it's true that it will be accessible via CVS,
   but a few years from deletion, people will forget it is there.  */

(I think that "10.31" is a typo: it should be "19.31".)

Given this very clear (IMHO) explanation, I don't understand your
original gripe about it:

Can you explain what you meant by that, now that you know why the old
code was left in the sources, rather than deleted?

Done (although it should be the default of any decent mail software).

I'm the list administrator, so if you need help with that, please mail
me privately.
