Bug report
Bug description:
In #138309 tarfile.TarFile.extract() has been modified to replace / in symlink targets with \ on Windows. I believe that the opposite normalization should be done in tarfile.TarFile.add().
I have noticed this in a downstream project that extracts tar archives generated by git dist, adds some additional files, and recreates the archive. When the git repository contains a symbolic link, the repacked archive contains symbolic link with the wrong path separators.
Before #138309, the extracted symbolic links on Windows were not functional (I believe) but the repacked archive had the same content as the original one. After #138309, this is not true anymore.
