The second line doesn't actually get pasted, so you are only pasting 1 line anyway-- which means mIRC is right, and there is no need for a confirmation. I see no problem with mIRC stripping the empty lines off the end of the content to optimize that specific case. It can't do it with empty lines in the middle of content, because that would require parsing the entire string (stripping lines off the end is a simpler process). Actually, I shouldn't say "can't", because it *could* do that as well, this is just a simple optimization, not a bug.
