Ah, that is correct.

I use M-x apropos RET buffer-process RET, and mouse-2 works for
"Function:".  When I hit enter while point is in "Function:", the
appropriate Help buffer is shown.

The bug is this:

When I use RET when point is on "get-buffer-process", the appropriate
Help buffer is shown.  This part does not change colors when the mouse
moves over it.  Therefore, mouse-2 is not always equivalent to RET in
an Apropos buffer.  I think it should be.  What do you think?

apropos-follow takes the 'item property at bol into account,
apropos-mouse-follow only takes 'mouse-face into account.  Why the
difference?  I agree, that only mouse-face advertizes the ability to
follow, but item provides the ability to follow.  So if possible, the
mouse should follow.  Even when not advertized.

Alternatively, the name of the symbol should also be advertized using
mouse-face.
