extensions: drop dead code trying to exclude deprecated disabled commands Here 'ext' is a tuple, which means ext.__doc__ describes about the Python tuple type. Fixing this would break 'hg help glog', which currently shows some nice explanation, so this patch just removes the dead code. $ hg help glog 'glog' is provided by the following extension: graphlog command to view revision graphs from a shell (DEPRECATED) (use 'hg help extensions' for information on enabling extensions)
