force:source:deploy fails with single CustomLabel in manifest

Summary

Fails to deploy using force:source:deploy when the package manifest contains a single CustomLabel.

Steps To Reproduce:

1. Create a package manifest with single CustomLabel, manifest/package.xml:

<?xml version="1.0" encoding="UTF-8"?>
<Package xmlns="http://soap.sforce.com/2006/04/metadata">

 <types>
   <members>FOO_BAR</members>
   <name>CustomLabel</members>
 </types>

 <version>45.0</version>
</Package>

1. Add CustomLabel to workspace, force-app/main/default/labels/CustomLabels.labels-meta.xml:

<?xml version="1.0" encoding="UTF-8"?>
<CustomLabels xmlns="http://soap.sforce.com/2006/04/metadata">
    <labels>
        <fullName>FOO_BAR</fullName>
        <language>en_US</language>
        <protected>false</protected>
        <shortDescription>Foobar label</shortDescription>
        <value>FooBar</value>
    </labels>
</CustomLabels>

1. Deploy

  sfdx force:source:deploy -x manifest/package.xml

Expected result

The CustomLabel should have been deployed to the target org. This is currently possible with Ant Migration Tool.

Actual result

ERROR: The CustomLabel named FOO_BAR was not found in the workspace.

Additional information

Changing the package manifest to use the CustomLabels type instead of CustomLabel works but this is deploying more than I want to push to the sandbox.

<?xml version="1.0" encoding="UTF-8"?>
<Package xmlns="http://soap.sforce.com/2006/04/metadata">

  <types>
    <members>*</members>
    <name>CustomLabels</members>
  </types>

  <version>45.0</version>
</Package>

Here is what works for me:

to pull from a Sandobx/Org:

  <types>
    <members>AcmeLabel</members>
    <members>BetaLabel</members>
    <name>CustomLabel</members>
  </types>

to push to a Sandbox/Org:

  <types>
    <members>*</members>
    <name>CustomLabels</members>
  </types>

– not great, not terrible, but it does the job.

This should be fixed by the Dec 12th release of the CLI.
