Hi,

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=13404 changed the behavior
of comint-previous-matching-input-from-input to keep point after the text
entered by the user instead of moving it to the end of the line. However, I
got reports that users prefer the old behavior (moving point to the end of
the line so they can immediately append text to the inserted history
entry). So I created a new customization option to switch between the old
and the new behavior. Please take a look.

Thanks.
