List format prints extra newlines/whitespace; behaves oddly with --query.

[binderjoe]

Like --output tsv, the default list format needs to suppress extraneous newlines. If you use:
$> az vm list-all --query "[].name"
You will see
[vm]

[vm]

[vm]

$>

The output should be:

$> az vm list-all --query "[].name"
[vm]
[vm]
[vm]
$>

For now, this is by-design, I think. The default format is list, which by default apply a line break after each entity

[yugangw-msft]

It appears, the query doesn't really work very with the "list" format, particularly when you use it to reduce the output and pipe to the next command. IMO, default to json makes more sense

[yugangw-msft]

Also, the "list" format will normalize the field name to be Pascal style, say from 'name' to 'Name', so you can't use it for projection.

I checked the status on this today. Running az vm listl --query "[].name" yields:

[
  "vm",
  "vm",
  "vm"
]

It seems this issue is fixed.
