GitWCRev.GetWCInfo COM object ignores file path (parameter 1)

What steps will reproduce the problem?

1. In chosen language (IDL - project requirement) create a GitWCRev COM object
2. Use the GetWCInfo member function e.g. oGitWCRev.GetWCInfo( filename, 0)
   a) where filename is a path to a repository on the local machine e.g. "c:\pathToRepository\trackedFileName"
   b) parameter 2 is a flag where 0 = include submodules, and 1 = exclude submodules
3. Access member variable of GitWCRev object:
   a) Revision
   B) Date
   C) Author
   D) HasModifications
   E) HasUnversioned
   F) IsGitItem

What is the expected output? What do you see instead?
Expected:
When filename points to a specific file HasModifications and IsGitItem should only reflect the status of that file (e.g. if the file is unmodified HasModifications=false, or if the file is not commited to the repository, IsGitItem=false). When filename points to a directory, HasModifications should only be true if files within that directory have modifications.

Actual:
HasModifications returns as true any time that any file in the entire repository has been modified, even when the file that has been modified exists at a directory level outside of the directory specified by filename. IsGitItem returns as true any time that the specified filename exists within the folder structure where the repository is located locally.
