The Solaris box I have a shell on, has gsed installed as a purely
optional third-party addon from a third-party package feed. As far as I
know, Solaris never did nor plans to ship "GNU bits like this".

Of course, the Git project *could* declare users must first build GNU
sed, then build Git. Or only build on boxes where the admin is a GNU
enthusiast. But that option seems unlikely and unattractive...
