Partly I use windows and partly linux.
My main requirement right now is for a stable and usable git under
windows.
Maybe git is not very usable under windows? I thought it had moved on
from there. But I would like to hear if this is so.

Right now Im on my linux box... so responding from memory of the
windows problems with git.el
1. With a detached head (ie something was checked out 'inside' a
branch) I got
    Branch:     fatal: ref HEAD is not a symbolic ref
    in git-status. I was suggested on the git mailing list to upgrade
git.el. Did it but this problem did not go away.
2. Later on trying other commands like commit, add etc I keep getting
    Wrong type argument: arrayp, nil

Well thought I'd do a little elisp debugging on that.
When I loaded git.el with edebug-all-defs I got:
Invalid read syntax: "Expected one of", stringp, "nil"

Note: That this is something in git.el that is triggering a bug (or at
least a deficit in edebug)
I edebugged pieces of the file and came to this that
is offensive to edebug
(defstruct (git-fileinfo
            (:copier nil)
            (:constructor git-create-fileinfo (state name &optional
old-perm new-perm rename-state orig-name marked))
            (:conc-name git-fileinfo->))
  marked              ;; t/nil
  state               ;; current state
  name                ;; file name
  old-perm new-perm   ;; permission flags
  rename-state        ;; rename or copy state
  orig-name           ;; original name for renames or copies
  needs-update        ;; whether file needs to be updated
  needs-refresh)      ;; whether file needs to be refreshed

I guessed that this is not really the problem (and Im not keen on
debugging edebug) so edebugged the rest of git.el, un-edebugged this
defstruct and tried...

The error is evidently coming from a ewoc-locate

[This happens on windows and not on linux; the defstruct offending
edebug error happens on both]
Anyhow this is getting too much into the innards of emacs so I did not
pursue it further.

So let me restate my question -- How to use git with emacs under
windows?
Does vc with git backend work?
Its quite ok to use vc for simple single-file-ish stuff and drop to
the command line for more gitly stuff
But if nothing works really properly under windows I wont waste too
much time
