[Feature Request] Support git subtree to reference a git repository from a prefix directory in another git repository

[andry81]

Currently i don't see the ability to use the git subtrees (better alternative to the git submodules) to represent a piece of directory in the GIT repo. Currently i can create multiple GIT repos from a single or several SVN repos, but can not make a reference repository in the GIT.

At least it was not mentioned here: https://techbase.kde.org/Projects/MoveToGit/UsingSvn2Git

Do you have plans to make it?
