[ryu-ichiroh]

Resolve: #1415

Briefly, this change fixes a bug that the rows do not match the lines on the screen.

• master

  

• ryuichiroh:issue-1415-multiline-highlights

  

Vim has a problem with multi-line text_prop not working properly. https://github.com/vim/vim/issues/11846 Therefore, I changed the code to add text_prop one line at a time.

The idea is simple because it's based on the code for Neovim. (https://github.com/prabirshrestha/vim-lsp/blob/master/autoload/lsp/internal/diagnostics/highlights.vim#L137-L163)
