Hi Thomas,

  Thanks for following up.  

  I believe we need a copyright assignment from you -- individual patch
looks trivial but they accumulate.  Furthermore, it would be better if
you had a write-after-approval account.  Since I have an interest in
this work, I may sponsor your account; however, we need a copyright
assignment from you.

This should be:

    new_name = XNEWVEC(char, strlen (last_real_name) + 10);

Similar remarks for other xmalloc.  Please, see whether they are
vector allocation of just single object allocation and use the
appropriate form.  Thanks!
