brotli --test --verbose should show a message

[stokito]

When running a integrity test brotli shows nothing and t his is correct according to unix philosophy.
But when I asked the brotli to be verbose it still didn't show anything:

$ brotli -vt goodarchive.br
$ brotli -vt corrupt.br
corrupt input [corrupt.br]

What do I expect is the same behavior as for gzip, xz and many other compressors:

$ gzip -vt goodarchive.gz
goodarchive.gz:	 OK
$ gzip -vt corrupt.br
gzip: corrupt.gz: not in gzip format

As you can see in verbose mode test shows a file name and status OK.

Could you make brotli to work similar with other compressors?

[eustas]

Surely. Will implement that soon (when get some free cycles =)

@eustas thank you. Also please note that gzip, uncompress, bzip2, lzip, lzma, xz, lzop compressors usually prints an output to stderr instead of stdout but rar and 7zip prints to stdout.
So I'm not sure what is a correct behavior but please implement according to some standard de-facto i.e. stderr.

[eustas]

Currently CLI prints something to stdout only for --help and --version, i.e. when user directly requested some output.
For "verbose" + "test" options stderr seems to be the only right destination, to make it consistent with other "verbose" outputs.

I think it is fixed now:

 ~$ brotli -tv gato.html.br 
Decompressed [gato.html.br]: 698 B -> 4.395 KiB
