vim-markdown blocks vim-gfm-syntax emoji conceals

[harriott]

vim-gfm-syntax seems to be working well alongside vim-markdown except that the latter (this plugin) blocks emoji conceal functionality (= vim-gfm-syntax/autoload/gfm_syntax/emoji.vim). This is a minor issue, but it might be easy to fix, or not, or worth the effort incase other markdown plugins have a similair conflict with vim-markdown. My temporary fix is to enable a gfme filetype for when I want emojis in a *.gfm, as described in the intro of my $vimfiles/syntax/gfme.vim.
