When multiple lines have been entered in the find/replace text box, maybe expand the text box to show that?

When multiple lines have been entered into the find/replace text box(s), it can be hard to tell, which can sometimes result in errors during find/replace operations. This is especially true if a multi-line value sneaks its way into your history when you want to repeat a previous find/replace.

So it would be nice if the text box expanded to show all the lines (perhaps up to 5 or so lines, after which a scrolling text window would probably be appropriate.
