Sorry for not providing a *.sh file that triggers the bug.

Try this recipe:

$ cd /path/to/trunk/emacs

$ cp -p autogen.sh autogen.sh.bak 

$ head -n730 config.guess >> autogen.sh 

$ emacs-23-1 -Q \
   --eval "(add-hook 'sh-set-shell-hook 'sh-learn-buffer-indent)" \
   -f cvs-update

- Hit RET (to confirm cvs directory)

- Move to the line with autogen.sh and do `=' (cvs-mode-diff)

- The window layout is *cvs* / *cvs-diff* (upper / lower window)

- Do `C-x o' (other-window) to jump to the *cvs-diff* buffer.

- Do `M->'

- Hit `C-c C-c' (diff-goto-source)

- The window layout is *indent* / autogen.sh (upper / lower window)

  ==> Bug

- Revert autogen.sh

  $ mv autogen.sh.bak autogen.sh 

Bye, Reiner.
