Provides two rings pointhistory-ring and pointhistory-auto-ring
for remembering positions of point.
If a command moves point over a long distance. The previous point position
is stored in pointhistory-auto-ring.
You can return to these point positions by the command pointhistory-auto-backward (bound to M-S-up).
This is most useful if you accidently moved point and want to return to the previous position.
If you want to remember a point position for later use you can call pointhistory-point2ring (bound to M-+).
Press M-up to rotate through the remembered point positions.
Stores also unexpected intermediate point positions of commands in pointhistory-auto-ring. Just keep pressing M-S-up to skip those positions.
