This is a very good thing!

But it reminded me that jumping from the *Help* buffer to the source
buffer still has one inconvenience: it selects the source buffer in a
different window.  It makes more sense to switch to the source buffer
in the same window, because the same text that is displayed in the
*Help* buffer, after switching will be visible in the docstring in the
source buffer.  So no information is duplicated on the screen.

For some time I used the following patch, and it's very convenient:
