bug#12943: 24.2.50; switch to help buffer with > 3-window-split

[Vitalie Spinu <spinuvit@gmail.com>]

Hi, 

If I have only one window in a frame. C-h v ... RET opens a help buffer, 
but does not switch to it.  Same with 2 windows in a frame.

If I have a 3-window-split, C-h v ... RET pops to the help buffer. This
is a bit annoying and might be indicative of some more severe underlying
problem.

I hope this is not an intended behavior.

Thanks.
