"include" files are listed multiple times in nuspec file

[guss77]

Using Write-NugetPacakge -GenerateOnly generates a nuspec file where each include header is listed multiple times.

I've seen files where each header is listed twice and files where there are 3 duplicated listings - this may be related to the way we specify includes:

• An autopkg spec that uses nuget { nuspec { files { includes: { ... } } } } generates two duplicate listings
• An autopkg spec that uses nuget { nuspec { files { nestedInclude: { #destination = ...; ... } } } } generates three duplicate listings

but this may be inaccurate - I don't have enough instances yet to tell.

The openssl package seems to suffer from this issue.
