you see them with esp, but they have Clear colour and glyph, so you don't see them with your own eyes. You can still attack master thieves with spells, ranged attack and so on.
attr_clear probably mean they have a colour of tile, on which there are standing, like clear hound or clear icky thing.
and char_clear is for no glyph i think
