   1.1 1.2 1.3 1.4
   2.1 2.2

   [...]

   Anybody knows about a hack to achieve jumping from 2.1 to 1.4.

Here's a quick and dirty hack:

[-- Attachment #1.2: vc-rcs-previous-revision.el --]
[-- Type: application/emacs-lisp, Size: 1232 bytes --]

[-- Attachment #1.3: Type: text/plain, Size: 14 bytes --]


Tested with:

[-- Attachment #1.4: mkfoo --]
[-- Type: application/shell-script, Size: 280 bytes --]

[-- Attachment #1.5: Type: text/plain, Size: 422 bytes --]


and:  C-x C-f /tmp/foo RET
      M->
      C-x v g
      p
      p
      p
      p
      p
      p

It's dirty because it calls rlog(1) directly, sidestepping the VC
abstractions, and what's worse, that info was already laboriously
computed in the process of preparing the annotation buffer, then
discarded (the infelicity is not limited to this function).  :-/
