tweak to apropos-command display

[Chong Yidong]

When apropos-command is displaying the keybindings associated with a
command, it often runs past the edge of the screen (esp. when displaying
M-x COMMAND RET) This makes the output very difficult to read.

A simple way to deal with this problem is to put the keybindings on their
own line. Opinions?
