What went wrong

When I use rls, it appears to output multiple error messages per error. For example, in this case it outputs three messages for one error. I can live with this, but it would be nice if spaces were inserted between the messages.

Reproducing the bug

I tested it with a bare ~/.config/nvim/init.vim contains these lines:

set nocp
call plug#begin('~/.local/share/nvim/plugged')
Plug 'w0rp/ale'
call plug#end()
let g:ale_linters = {'rust': ['rls']}

Feel free to create a pull request to address this. Someone might have already made the message more readable if you use :ALEDetail.

[rymdbar]

This seems to be a rls specific issue. That language server has been deprecated and sunset. With it rls no longer available nor working, can we suggest this ticket to be closed?
