OK, time for some replies. First of all:
I sincerely apologise that my remark caused people offence!
Apology accepted - and thank you for doing so in a fresh post rather than as an edit, otherwise I might have missed it
There is a bit in the Frequently Asked Questions on the Help pages that explains that posts can only be edited for 24 hours:

Yes, I'd seen that, but I was wondering if it would help to suggest that if subsequent posts have been made, any editing should be limited to typos etc.
If members like Arthur are really concerned about serious editing making a nonsense of replies, could I suggest that they could always quote the original when they reply.
In the thread that prompted my initial message here, mine was the second response (so not separated by a whole load of scrolling) and I was replying to the whole of the message rather than only one bit, so quoting seemed unnecessary.
In this case, even quoting the whole message as it was at that time would have eventually looked silly because (a) the OP added the comment as an extra note on the end, and (b) it would then have appeared that I had selectively quoted the problem as originally posed and ignored the OP's resolution of it. (It still does look a bit like that, only without the quote.)
It may be hard to believe, but I do understand the wish to edit one's own posts. Quite often, I rush off a reply in the hope of being one of the first to answer a question, and then have to go back to deal with typos or something I've forgotten.
But this question seems to come down to finding the right balance between a poster's desire to edit, and other people's annoyance when it is done in a way which makes
their posts look silly or unnecessary.
