Perhaps such portions of text should only be cut-n-pasted as rectangles. > What does it *mean* to copy a character from inside environment > `larum' which is inside environment `lirum' and insert it somewere > else? What should that character look like in its new location? This is a hard problem. I don't have solutions, but I can say that one very widespread non-free word processor sometimes does _HORRIBLE_ things when text is copied from a fragment that uses some non-trivial style to another portion of the document. My suggestion would be to stick to the KISS principle as much as it's feasible.
