Subject: vim-patch:8.2.2199: first write after setting 'eol' does not have NL
 added
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Problem:    First write after setting 'eol' does not have NL added. (Tomáš
            Janoušek)
Solution:   Only use b_no_eol_lnum when doing a binary write. (closes vim/vim#7535)
