DTG can't locate functions when module defines a DefaultCommandPrefix

[ebekker]

When a module defines the DefaultCommandPrefix property in its manifest, DTG can't properly locate/inspect help details of the functions (cmdlets) exported from the module.

I've verified this is true for both binary and script modules.

The source of the problem appears to be in the Generate-FunctionPages routine -- where it's getting the list of commands from the Get-Command -Module $moduleName call -- this returns a set of System.Management.Automation.FunctionInfo instances.

While each instance appears to have correct individual about each command, when you invoke the .ToString() on this type, it returns a form of the command where the DefaultCommandPrefix is doubled.

For example, if I have a module TestModule that defines a DefaultCommandPrefix of TestMod, and two exported functions:

• Get-Min
• Get-Max

Then by default, upon importing this module, I would expect these routines to become available as:

• Get-TestModMin
• Get-TestModMax

But when the FunctionInfo.ToString() returns them as:

• Get-TestModTestModMin
• Get-TestModTestModMax
