Cursor jumps back to beginning of the buffer after format-all-buffer before save

Followed the following step to reproduce:

• open a file (I am using C file).
• split several windows (same contents), change cursor position for each window.
• change some content.
• enabled format-all-mode, and save, or directly call format-all-buffer.
• cursor position maintained only for the focused window, other windows cursors are set to the beginning of the window.

I saw we have function to keep current window cursor position, just wondering if we can also check and save other windows' cursor position.

Sorry, I missed this issue for some reason. I agree that it'd be nice to preserve the position in other windows. Unfortunately I don't immediately recognize what causes the problem, and don't have time to investigate. If someone else finds a solution, I'll be happy to merge it in.

In general, multi-window stuff is a bit of a PITA to figure out Emacs, so good luck to any brave soul who looks into it :)
