I am not seeing any changes or updates to the git-crypt package since
this issue was opened, but I am also not seeing the full path to the
git-crypt binary when I "git init" and "git-crypt init" a new repo:

$ cat .git/config
[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[filter "git-crypt"]
        smudge = \"git-crypt\" smudge
        clean = \"git-crypt\" clean
        required = true
[diff "git-crypt"]
        textconv = \"git-crypt\" diff
