bug#13146: [PATCH] help-for-help interferes with buffer order, and displays help in too many windows

[Kelly Dean]

In 24.2, do emacs -Q, then
M-x split-window RET C-x b foo RET C-x b bar RET C-h C-h C-g C-x b
It defaults to *Help*, but it should default to foo; transiently displaying 
help-for-help shouldn't modify the buffer order.

Now do C-g C-h f mark RET C-x o C-h C-h
It shows the help-for-help page in both windows, but it should show it in only 
one.

The attached helphelpbug.patch fixes both problems. I'm not bothering to submit 
separate reports for the two since it's a one-line patch.
