These patches certainly help things along. The git init command now
completes and and I can remove existing git repositories (which I could
not before).

I was unable to get a git clone to complete (hangs at receiving objects
0%). I was able to create a new repository, edit a file, add it, and
commit it. "git log" return nothing, same with git show HEAD:

sh-4.2# cd 9ptest/
sh-4.2# ls
world
sh-4.2# git status
# On branch master
nothing to commit (working directory clean)

(so it doesn't list "world" as untracked nor as changed but not
committed). It has been committed.

sh-4.2# git log
sh-4.2# git show HEAD
sh-4.2# git whatchanged HEAD

A couple nitpics below:

EOL whitespace ^


The same issue exists with the _rename patch following this one.
