I thought that you really know what you are talking about, but now I have no
doubts that you don't:
E_IUSE=${E_IUSE// X } - deletes every X with whitespace around it.
E_IUSE=${E_IUSE#X } - deletes X if there is one at the beginning
E_IUSE=${E_IUSE% X} - deletes X if there is one at the end
No more X left.
