What happens if you change this:

  Lisp_Object icon_title_name_format
    = pure_list (empty_unibyte_string,
                 build_pure_c_string ("%b - GNU Emacs at "),
                 intern_c_string ("system-name"));

to say this instead:

  Lisp_Object icon_title_name_format
    = pure_list (empty_unibyte_string,
                 build_pure_c_string ("GNU Emacs at "),
                 intern_c_string ("system-name"));

This code is in xdisp.c.  The change I propose removes the "%b - "
part from the argument to build_pure_c_string.
