You can avoid hardcoding it by using
(vc-call print-log file <buf> ...)
See lisp/vc/vc.el's commentary where it describes
;; * print-log (files buffer &optional shortlog start-revision limit)
;;
;; Insert the revision log for FILES into BUFFER.
;; If SHORTLOG is true insert a short version of the log.
;; If LIMIT is true insert only insert LIMIT log entries. If the
;; backend does not support limiting the number of entries to show
;; it should return `limit-unsupported'.
;; If START-REVISION is given, then show the log starting from that
;; revision ("starting" in the sense of it being the _newest_
;; revision shown, rather than the working revision, which is normally
;; the case). Not all backends support this. At present, this is
;; only ever used with LIMIT = 1 (by
;; vc-annotate-show-log-revision-at-line).

You can do
(with-current-buffer <buf>
(vc-exec-after
(lambda ()
<the-code-to-run-after-print-log-is-done>)))
[ Here, I presume you're using -*- lexical-binding:t -*-, which I strongly
recommend. ]
