I am using your library in a custom project which does not adhere to usual UNIX standards when naming the commands. It uses commands akin to PowerShell commandlets as in Write-Output. I wanted to rename help to Get-Help with a custom hook (either using mock or manually overriding Module.prototype.load) which had some since Get-Help Write-Output would not print the expected help for the particular Write-Output command.
After reverting my rename it turns out with your default help Write-Output the output is still Invalid command. After looking through the code for far too long it turns out that this line the culprit:
Your default help command is calling toLowerCase on the argument and then looking for a write-output command. However debugging yields that the name of the command is not altered when creating it and still being Write-Output.
In order to fix this it is only necessary to remove the linked call toLowerCase. Unfortunately there are still two occurences of it:
I haven't figured out what they are exactly doing and whether my first change will break something. Once I know more and was able to test the change I am considering to open a pull request to fix this.
