eshell tag 'eshell-replace-command

[Leo]

Hello,

I am trying to wrap git in eshell/git. Here is a minimal example to
demonstrate the problem:

(defun eshell/git (&rest args)
  (throw 'eshell-replace-command
         (eshell-parse-command (eshell-search-path "git") args)))

when run 'git help' in eshell, I am getting:

  No catch for tag: eshell-replace-command, (progn (eshell-trap-errors
  (eshell-named-command "/usr/local/bin/git" (list "help"))))

A similar construct in eshell/cat (em-unix.el) works fine. Any idea
why eshell/git fails? Thank you in advance.
