Feeding Get-Command output to itself via the pipeline - useful if you want to force loading of all modules in the context of reflection - doesn't work as expected.

It looks like a new parameter set with a System.Management.Automation.CommandInfo-typed parameter would have to be introduced to support that.

Steps to reproduce

# OK
('Add-Content', 'Get-Content' | Get-Command).Name | Should -Be 'Add-Content', 'Get-Content'

# Fails
(Get-Command 'Add-Content', 'Get-Content' | Get-Command).Name | Should -Be 'Add-Content', 'Get-Content'

Expected behavior

Both tests should succeed.

Actual behavior

The 2nd test fails, because the only CommandInfo object output is the one for Add-Content

Expected @('Add-Content', 'Get-Content'), but got 'Add-Content'
