Exactly.  But this means that you need to populate a new separate map
'gdb-repeat-map' specific to 'gdb' commands.  Also I noticed that the
current name of 'gud-repeat-map' is wrong.  It should be renamed to
'gud-gdb-repeat-map'.  So other debuggers could populate own repeat-maps
named e.g. 'sdb-repeat-map', 'jdb-repeat-map', 'perldb-repeat-map', etc.
