bug#1277: 23.0.60; vc revert dialog may need new lines

[robert marshall <robert.marshall@tnei.co.uk>]

If you go into a vc-dir directory and mark a number of edited files
and then off the menu select 'Revert to base version', the dialog which
asks whether you want to discard changes lists all the files without
any new lines between the file names!

The yes/no buttons may then be an awful long way across the screen!

I've managed to cause emacs to hang with one revert request - maybe
because the dialog was just too wide?

Thanks
