Fetch specific commit?

Is there a way to fetch a specific commit? I tried:

plugman install ... --plugin cordova-plugin-keyboard#1234
plugman install ... --plugin https://github.com/cjpearson/cordova-plugin-keyboard#1234

but they all "Failed to fetch plugin from registry".

Start by reproducing the two plugman install commands in the issue and inspect how plugin URLs and registry fetches are handled. Determine the supported syntax for selecting commit 1234, then verify that an install from the registry or GitHub URL completes successfully.
