Vimr: Reread file when window gains focus

[nornagon]

If a file has been changed on disk, MacVim prompts you when the window gains focus and asks if you want to reload that file from disk. It'd be awesome if VimR did the same! I've been confused a few times when switching back to VimR and seeing outdated content.

You can set that in your .vimrc or init.nvim or wherever your config lives. I have the following:

set autoread
autocmd FocusGained,BufEnter,CursorHold,CursorHoldI * if mode() != 'c' | checktime | endif
autocmd FileChangedShellPost *
      \ echohl WarningMsg | echo "File changed on disk. Buffer reloaded." | echohl None

Works nicely, and prints a little message in the statusline when files get reloaded.

@nornagon Does the above snippet by @bowmanmike work for you?

I was hoping for some kind of dialog allowing me to choose what to do, like MacVim does, but the snippet is better than nothing I guess.
