Add Windows Context Menu file command for "git difftool %1"

Question

I am trying to add a file context menu option to execute git difftool %1 (which is configured to use Beyond Compare 4). I've got the context menu showing up with the icon I want but can't get Beyond Compare to pop up with the file diff.

I've tried setting the default string value to the following but it didn't work.

HKEY_CLASSES_ROOT\AllFilesystemObjects\shell\BeyondCompare.Diff\command
(Default)
   = "C:/Program Files (x86)/Beyond Compare 4/BComp.exe" "$LOCAL" "$REMOTE"
   = cmd /c git difftool %1
   = "C:\Program Files\Git\git-bash.exe" /dir %v. git difftool %1

And here is the registry key to show the above command in the file context menu.

HKEY_CLASSES_ROOT\AllFilesystemObjects\shell\BeyondCompare.Diff
(Default) = Git Diff
Icon = C:\Program Files\Beyond Compare 4\BCompare.exe

What should I set my command string to so this works?

Instead of trying to create a custom context menu entry, it might be easier to use TortoiseGit to provide context menu access to Git, then configure TortoiseGit to use Beyond Compare as an external diff and merge tool.
