Emacs on Windows doesn't really support message boxes (a.k.a. "dialog
boxes"), except for simple Yes/No questions popped up by yes-or-no-p.
For other messages, such as this one, Emacs on Windows emulates dialog
boxes by menus, and in a menu an item cannot contain a newline.

In this case, we faithfully pass the original string with a newline to
the MS-Windows menu API, and I believe it is dropped by Windows when
it displays the menu.

IOW, this is a missing feature: dialog boxes are not fully supported
on MS-Windows.
