Re: master 73f37da: Disable undo in the process buffers of a JSONRPC connection

[João Távora]

Hi Stefan,

They are indeed intended to be seen by the user. They hold important communications between server and client, and I ask users to post their contents when making Eglot bug reports.

Well I suppose the stdout one less useful than stderr.

And this is more of an LSP requirement than an jsonrpc one. I could theoretically make Eglot tell. Jsonrpc to promote the buffer's visibility, but that seems like overkill right now.

Assuming those buffers are only used internally and are not intended to
be displayed to the end-user (other than for debugging purposes), then
using buffer names with a leading space should take care of this
(undo is disabled by default in those buffers).

If you're already using a leading space in those buffers's names, then
I wonder how/why their undo was enabled in the first place.
