Re: mcedit: undo warning

It looks like a bug for me. In mcedit I have next warning when remove block of text (when length is large than 16384): "Block is large, you may not be able to undo this action"

But actually I can undo only when remove block of text with length less than 8190.

So, when I remove block of text where 8190 <= length <=16384 I don't get any warning and can't undo this action.

That's correct, the condition in question is

    (end_mark - start_mark) > option_max_undo / 2


    int option_max_undo = 32768

It looks like it should be option_max_undo / 4, according to your observation, but I have no idea why and how come...

In any case, please report this bug on the Trac, because otherwise this will get lost on the list.

Sincerely yours,
Yury V. Zaytsev
