Issue

Rich now blacken-mode does not save-excursion in most of the cases. This breaks the flow of the coding, because every time I run blacken-buffer, or it is run automatically, the cursor goes either to the beginning of the buffer, or to some random place. This makes it impossible to use auto-save modes such as super-save, which are extremely useful. This bug is preventing me from using blacken-mode, which is otherwise extremely useful.

You could try https://github.com/raxod502/apheleia to cut down on unexpected point movement. It has some problems with undo history though. radian-software/apheleia#15

For me the point position is correctly saved in the window where the focus is (not sure what's the correct term for that) however if I have another window with the same buffer, the point position in that other window is lost, and that is somewhat annoying.
