Lsp-mode: *lsp-log* buffer undo overflow

[axelson]

Describe the bug
If running a server that generates a very large amount of output then the undo info can overflow

To Reproduce
I don't have this, but if it's needed I can generate one

Expected behavior
The undo buffer should not overflow because undo is not needed in this read-only buffer

Which Language Server did you use
ElixirLS (while developing on the server)

OS
Arch Linux

Error callstack
N/A

We should probably stop undo/redo in the log buffer? 😕

Thanks for reporting this issue to us! 👍

[axelson]

yeah it seems like unnecessary memory use

This should fix by #2376. Feel free to reopen this issue if you find out useful! Thanks! 😄
