I changed my code to wait until the 'Git' process completes. Luckily "vc-call-
backend" returns the async process.
#+begin_src emacs-lisp :var limit="" :file test.log :exports results
;; Most of this code is copied from vc.el vc-print-log
(when (vc-find-backend-function (vc-backend (buffer-file-name (current-buffer)))
'print-log)
(let* ((limit (if (numberp limit) limit vc-log-show-limit))
(vc-fileset (vc-deduce-fileset t)) ;FIXME: Why t? --Stef
(backend (car vc-fileset))
(files (cadr vc-fileset)))
(with-temp-buffer
(let ((status (vc-call-backend backend
'print-log
files
(current-buffer))))
(while (not (eq 'exit (process-status status)))
(sit-for 1 t))
(buffer-string)))))
#+end_src
