    Fixup 71623b88: change semantics of "delete" LFUNs again
    
    Instead of specifying "force" to disable the deletion protection
    mechanism, invert the default so that "confirm" is needed to activate
    it. The idea is to keep the lfun reasonable for scripting and add a
    special argument for interactive use.
    
    Document in release notes.
    
    Update LFUN.lyx documentation
    
    Update bind files.
    
    Add conversion step to prefs2prefs_lfun.py.
