Support skywind3000/asyncrun.vim as replacement for tpope/vim-dispatch

[mcepl]

https://github.com/skywind3000/asyncrun.vim should be a replacement for tpope/vim-dispatch using async capabilities in vim8. The only usage of vim-dispatch I can find for me is in this function in vim-fugitive:

function! s:Dispatch(bang, args)
  let cd = exists('*haslocaldir') && haslocaldir() ? 'lcd' : 'cd'
  let cwd = getcwd()
  let [mp, efm, cc] = [&l:mp, &l:efm, get(b:, 'current_compiler', '')]
  try
    let b:current_compiler = 'git'
    let &l:errorformat = s:common_efm
    let &l:makeprg = g:fugitive_git_executable . ' ' . a:args
    execute cd fnameescape(s:repo().tree())
    if exists(':Make') == 2
      noautocmd Make
    else
      silent noautocmd make!
      redraw!
      return 'call fugitive#cwindow()'
    endif
    return ''
  finally
    let [&l:mp, &l:efm, b:current_compiler] = [mp, efm, cc]
    if empty(cc) | unlet! b:current_compiler | endif
    execute cd fnameescape(cwd)
  endtry
endfunction

I guess just adding another branch to that if statement should be enough?

Don't think of it as supporting dispatch.vim. Think of it as supporting any plugin that provides a :Make command. This is why I picked a generic command name. Much simpler for new async runners to provide a :Make command than for me to update half a dozen plugins.

Of course, another option would be to make vim-dispatch use native asynchronous capabilities of vim8 as well and make asyncrun redundant. ;)

That would be great, though I'm pretty content with my setup so it hasn't been a high priority for me.

Dispatch does use jobs now, fwiw.
