It doesn't convince me. I haven't seen any website in recent times constructed with text hyperlinks surrounded by the < and > signs. One would be wasting energy doing it anyway since you should be typing < and > in place of the characters in a HTML document anyway. Why should Khaled rejig mIRC to cater for such an outdated practice? Try fixing the stupid way the bot quoted URLs instead of asking others to fix bugs that don't exist.
As far as I know, the makers of mIRC claim compliance only with RFC1459, the IRC related RFC. As mIRC is an IRC client then this is probably the most appropriate standard to comply with.
