gEDA-cvs: CVS update: o_misc.nw

[cvspsrv@xxxxxxxx]

  User: cnieves 
  Date: 05/11/18 15:31:48

  Modified:    .        o_misc.nw o_undo.nw
  Log:
  Changed autosave code so the timer callback doesn't do the
  
  autosave backups. Now are made within o_undo_savestate, so
  
  backups will ONLY be saved when there was a change to the 
  
  schematic and there was a timeout of the autosave timer.
