Subject: 25.1; vc-dir for CVS repositories list all files as if from toplevel
 directory
Date: Tue, 26 Jul 2016 23:02:39 +0300

When a directory is viewed via VC (‘vc-dir’), when that directory is a
CVS directory, all files that are edited, whether in that directory or
in its subdirectories, are listed as if they were in the toplevel
directory of the repo.

Example (25.1):

,----
| VC backend : CVS
| Working dir: [deduced]
| Repository : [deduced]
| Module     : emacs.d
| 
| 
|                          ./
|     edited               eval-sexp-fu.el
|     edited               gk-org.el
|     edited               gk-utils.el
|     edited               gk.el
`----

Same directory, in 24.5:

,----
| VC backend : CVS
| Working dir: [deduced]
| Repository : [deduced]
| Module     : emacs.d
| 
| 
|                          ./
|                          gk/
|     edited               gk/gk-org.el
|     edited               gk/gk-utils.el
|     edited               gk/gk.el
|                          site/
|     edited               site/eval-sexp-fu.el
`----

Commands like vc-diff from this buffer (via ‘=’) fail, complaining it
can't find the VC backend.

Reproduction:

- Modify a tracked file in a submodule of a toplevel CVS module
- Call ‘vc-dir’ on the toplevel module
- Run a command on the modified file.

This is the stacktrace I get from ‘vc-diff’ (‘=’ in vc-dir) with
‘debug-on-error’ t:

,----
| Debugger entered--Lisp error: (file-error "Cannot open load file" "No such file or directory" "vc-nil")
|   require(vc-nil)
|   vc-find-backend-function(nil make-version-backups-p)
|   vc-call-backend(nil make-version-backups-p "[deduced]/emacs.d/gk-org.el")
|   vc-version-backup-file("[deduced]/emacs.d/gk-org.el" nil)
|   vc-cvs-diff(("[deduced]/emacs.d/gk-org.el") nil nil "*vc-diff*" t)
|   apply(vc-cvs-diff (("[deduced]/emacs.d/gk-org.el") nil nil "*vc-diff*" t))
|   vc-call-backend(CVS diff ("[deduced]/emacs.d/gk-org.el") nil nil "*vc-diff*" t)
|   vc-diff-internal(t (CVS ("[deduced]/emacs.d/gk-org.el") nil nil nil) nil nil t)
|   vc-diff(nil t)
|   funcall-interactively(vc-diff nil t)
|   call-interactively(vc-diff nil nil)
|   command-execute(vc-diff)
`----

If I try to see the version log, via ‘l’ in the *vc-dir* buffer,  I get
the ‘*vc-change-log*’ buffer with these contents:

,----
| cvs log: nothing known about gk-org.el
