bug in mail.c:getOneAddress

Sorry if this was reported before - I searched the gnats-prs archive for
getOneAddress but didn't find this one.

The getOneAddress routine has some code to strip off trailing whitespace,
but this goes a bit too far, causing bogus inputs to a later routine and a
seg fault on my RHEL 3.0 box.  Here's the original code:

  while (addr >= addrStart
        && isspace((int)(unsigned char)*(addr-sizeof(*addr))))
    {
      addr--;
    }

but the first test should be just "addr > addrStart".  To reproduce this,
just make sure an empty string is passed to getOneAddress.
