" Use toggle_option_flag.vim plugin to bind quick toggle actions for some
" 'formatoptions' flags:
"
" a - Automatically format paragraphs, reapplying the wrap on every text
"     insertion or deletion; sometimes I want this and sometimes I
"     don't, it particularly varies when typing prose in Markdown that
"     includes headings and code
" c - Automatically wrap comments at 'textwidth' (which I allow the filetypes
"     to set for me)
" t - Automatically wrap text at 'textwidth' (as above)
"
