`cargo-limit` invoke `CARGO_OPEN` twice per run

[casey]

I believe that cargo-limit is invoking CARGO_OPEN twice per run.

I'm working on a custom-function to populate the quickfix list:

function! g:CargoLimitOpen(result)
  cgetexpr []
  let files = a:result['files']
  for file in files
    caddexpr file['path'] . ':' . file['line'] . ':' . file['column']
  endfor
endfunction

However, this function is getting called twice every time I run cargo lcheck, first with:

{'files': [{'level': 'error', 'path': '/Users/rodarmor/src/agora/src/main.rs', 'column': 1, 'line': 5, 'message'
: 'expected one of `!` or `::`, found `#`'}], 'workspace_root': '/Users/rodarmor/src/agora'}

And then with an empty object:

{'files': [], 'workspace_root': '/Users/rodarmor/src/agora'}

Since my a:CargoLimitOpen this has the effect of populating and then immediately clearing the quickfix list.

Thanks for reporting this! I pushed a partial fix, so at least in most cases this shouldn't happen anymore.

Should work correctly now.

I actually broke #13 with initial partial fix. Reverted it, should be working well now.
