Since that original patch, the codebase was moved out of contrib and is now scalar.c alongside the other git source files. Remaining a seperate command rather than a subcommand is motivated by command line backwards compatibility for users of the c version from microsoft/git, but also for users of the older C# version. If they did git-scalar then they would still need a contrib subfolder command wrapper executable (not just a script, as many users are on windows and rely on it being an executable, not just a bash script).
