Close echo panel if it is empty

The message would show up during the scanning, and disappear when the scanning is done and leave the panel open.
Close the panel if it is empty, and try to preserve messages if it is useful.

Just a heads up: we're actually thinking of deprecating coala-vim in favour of other code analysis plugins that do exactly the same thing.

[perplexedfingers]

cool, what might be the alternative?
syntastic?

[adtac]

Neomake looks very promising. Syntastic looks pretty neat too.

[perplexedfingers]

How can I make coala into Neomake?

[adtac]

@r2qokk I still haven't looked into it. Soon enough, though. Do you have any experience with syntastic? If so, we'd gladly accept a patch describing how to use coala in syntastic.

[perplexedfingers]

I never go deep into syntastic.
I try to write some markers in Neomake, but they does not work as I expected.

let g:neomake_python_coala_maker = {
      \ 'args': ['--no-config',
      \          '--bears=CPDBear,PEP8Bear,PyImportSortBear,PyUnusedCodeBear,RadonBear',
      \          '--files']}

This setting produce nothing when I execute :Neomake coala
