You can go further back by looking at the old-releases, found through:

 http://sourceware.org/gdb/download/

On gdb-2.51, I see this:

              if (!strcmp (arg, "-se"))
                {
                  exec_file_command (argv[i], !batch);
                  symbol_file_command (argv[i], !batch);
                }


At revision 1.1 in CVS we have:

          exec_file_command (execarg, !batch);
          symbol_file_command (symarg, 0);


So at some point in time, the from_tty argument was changed to
a hardcoded 0.

Why that was so, I don't know.  I like gdb's output with
Doug's suggestion.

(BTW, looking through such old gdb's sources can be
quite informative sometimes, it's like looking at a
smaller prototype sketch of current gdb.  I keep copies
of those sources around myself, and sometimes peek them.)
