My comment wasn't meant to knock C++; it was to point out that Linus' opposition to the language is well-documented, and an official git-rewrite in C++ is very unlikely.
Linus is almost entirely uninvolved with git these days, though. `git log --author=Torvalds` finds no commits in 2015 or so far this year, three patches in 2014, none in 2013, five in 2012, four in 2011... if the git core team felt using C++ was a possible course, Linus would not be involved in the decision.
(That's probably why I misunderstoood your statement an argument against C++ on its own merits.)
