bug#70396: 30.0.50; Eglot, rust-analyzer buffer formatting, and track changes errors

[Steven Allen via Bug reports for GNU Emacs, the Swiss army knife of text editors]

When formatting a specific rust file with with `eglot-format-buffer`
(rust-analyzer LSP), I'm getting:

* Track changes errors (below).
* An `args-out-of-range` error in `replace-buffer-contents`.

To reproduce:

1. Checkout `https://github.com/Stebalien/xattr/`. I can try for a
   minimal reproducer if necessary.
2. Install rust-analyzer.
2. Run `emacs -Q`
3. `M-x find-file "src/sys/linux_macos.rs"`
   (https://github.com/Stebalien/xattr/blob/master/src/sys/linux_macos.rs).
4. `M-x rust-ts-mode`
5. `M-x eglot`
6. `M-x eglot-format-buffer`

bug#70396: Acknowledgement (30.0.50; Eglot, rust-analyzer buffer formatting, and track changes errors)

[Steven Allen via Bug reports for GNU Emacs, the Swiss army knife of text editors]

One additional detail I forgot to mention: repeatedly calling
`eglot-format-buffer` starts to corrupt the text the end of the buffer
(but rust-analyzer may be to blame for that one).

Adding Stefan, as I think this might be related to the recent
track-changes changes.

Thanks for the nice bug report.
Will look into it ASAP,

I could reproduce this in a C mode buffer (and hence save me the
trouble of installing more tools).
I pushed the patch below to `master` which should fix the problem.
Can you confirm it's fixed in your side as well?
