Subject: bug#19312: 25.0.50; `vc-annotate-show-diff-revision-at-line' fails under Subversion
Date: Mon, 8 Dec 2014 17:32:08 +0000

Visit a Subversion working file, type “C-x v g” (`vc-annotate’), and
when the annotate buffer is loaded, type "d"
(vc-annotate-show-diff-revision-at-line). The error backtrace is:

Debugger entered--Lisp error: (wrong-number-of-arguments (1 . 4) 5)
  vc-svn-diff(("c:/temp/test.txt") t "17246" #("17247" 0 5 (fontified
t invisible vc-annotate-annotation)) "*vc-diff*")
  apply(vc-svn-diff (("c:/temp/test.txt") t "17246" #("17247" 0 5
(fontified t invisible vc-annotate-annotation)) "*vc-diff*"))
  vc-call-backend(SVN diff ("c:/temp/test.txt") t "17246" #("17247" 0
5 (fontified t invisible vc-annotate-annotation)) "*vc-diff*")
  vc-diff-internal(t (SVN ("c:/temp/test.txt")) "17246" #("17247" 0 5
(fontified t invisible vc-annotate-annotation)))
  vc-annotate-show-diff-revision-at-line-internal(t)
  vc-annotate-show-diff-revision-at-line()
  funcall-interactively(vc-annotate-show-diff-revision-at-line)
  call-interactively(vc-annotate-show-diff-revision-at-line nil nil)
  command-execute(vc-annotate-show-diff-revision-at-line)

This is because `vc-svn-diff' takes 1-4 arguments:
  (defun vc-svn-diff (files &optional oldvers newvers buffer) [...])

...but is called with 5 from `vc-diff-internal':
  (vc-call-backend (car vc-fileset) 'diff files async rev1 rev2 buffer)
