Describe the feature

It would be nice to have a file's edit history preserved when the file is renamed, so that undo works even after the file is renamed.

Provide background

Currently, after renaming a file, that file's edit history is lost, such that attempting to undo (ie: pressing the u key) within the file is unable to return the file to any state that it was in prior to the rename.

For my specific use-case, I have the vim option, undofile, set to true, so edit history is stored in an undo file. Implementing this feature may be as simple as renaming the undo file when performing a rename or a file move operation?

What is the significance of this feature?

nice to have

Additional details

Thank you for this great plugin! It is a daily driver for me, one of the most useful plugins available for neovim.

I don't usually do feature requests these days because I have so little free time, but this was such an interesting question that I had to find out if it works. Turns out, it does!
