patch 9.0.1790: Redundant LSP Content-Type header Commit: https://github.com/vim/vim/commit/8fbd9449e71f2ad93e594be575209a7424eb093e Author: Magnus Gro? <magnus@mggross.com> Date: Sun Aug 27 00:49:51 2023 +0200 patch 9.0.1790: Redundant LSP Content-Type header Problem: The Content-Type header is an optional header that some LSP servers struggle with and may crash when encountering it. Solution: Drop the Content-Type header from all messages, because we use the default value anyway. Because pretty much all popular LSP clients (e.g. coc.nvim, VSCode) do not send the Content-Type header, the LSP server ecosystem has developed such that some LSP servers may even crash when encountering it. To improve compatibility with these misbehaving LSP servers, we drop this header as well. Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Magnus Gro? <magnus@mggross.com>
