GetVersion target does not update RepositoryBranch nor RepositoryCommit

[dittodhole]

This is an idea, to enhance stamping nuget packages created by sdk projects:
One could update the RepositoryBranch and RepositoryCommit msbuild properties accordingly in

GitVersion/src/GitVersionTask/buildMultiTargeting/GitVersionTask.targets

Line 55 in a4325e0

<PropertyGroup Condition=" '$(UpdateVersionProperties)' == 'true' ">

My current workaround is as follows (somewhere in your .csproj-file):

<Target Name="UpdateRepositoryBranch" BeforeTargets="GenerateNuspec">
  <PropertyGroup>
    <RepositoryBranch>$(GitVersion_BranchName)</RepositoryBranch>
  </PropertyGroup>
</Target>
<Target Name="UpdateRepositoryCommit" BeforeTargets="GenerateNuspec">
  <PropertyGroup>
    <RepositoryCommit>$(GitVersion_Sha)</RepositoryCommit>
  </PropertyGroup>
</Target>
