Why would the question of whether an *element* was modified even come up? That seems like a red herring, bound only to confuse people. The question that arises for users is about sharing/modification of the list structure, not elements. (Yes, of course an element can itself be a list.) There is nothing wrong with letting users know the actual behavior. It would be helpful to provide the kind of information that Emacs provides (and all Lisps provide) for `member': "The value is actually the tail of LIST whose car is ELT." But the main point - the point of the bug report, is that it is not correct to say, as we say now, that `remq' "Returns LIST with all occurrences of ELT removed." It does that only when all of the ELT occurrences occur before any non-ELT occurrences.
