The "Rename Page" feature suggests incorrect name

The "Rename Page" feature suggests incorrect name

The Rename Page function brings up a small dialog with the Page Name edit box pre-filled.

It should be pre-filled with the current page name, so that it can be edited easily.

Instead, it contains the current page name, but with all spaces replaced with hyphens.

Apparently this is using logic applicable to setting a new URL or something.
