[PATCH] minor nit in read_tilde_fields

[Klee Dienes <klee@apple.com>]

The following patch fixes what I suspect is an "oops" in the 2002-10-11 
patch to stabsread.c:

2002-10-16  Klee Dienes  <kdienes@apple.com>

         * stabsread.c (read_tilde_fields): Use name[sizeof(vptr_name)-2]
         to get the last character of a char[] buffer, not
         name[sizeof(vptr_name)-1].
