When I first tried to use the new markdown commands to show a markdown file, it seemed obvious to me that I'd just run:

# Expected:
Show-Markdown .\README.md

but that doesn't work. You have to execute this instead:

# Actual:
ConvertFrom-Markdown -path .\README.md -AsVT100EncodedString | Show-Markdown

It seems to me that Show-Markdown should have a Path parameter set so that you can simply specify the path to a markdown file to be shown.
