patch 8.0.0227: crash with ff=dos when first line in file has no CR commit https://github.com/vim/vim/commit/2aa5f696b91a51f29873e340de4bdc182e1e8dd4 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Jan 24 15:46:48 2017 +0100 patch 8.0.0227: crash with ff=dos when first line in file has no CR Problem: Crash when 'fileformat' is forced to "dos" and the first line in the file is empty and does not have a CR character. Solution: Don't check for CR before the start of the buffer.

" For Yiddish capitals should not be checked.  But only change the
" 'spellcapcheck' option when it is not at its default value.
