Hi there,

Michael Heerdegen developed a patch for the problem.

Feedback: apply patch - not quite successfull


When trying to apply the patch

M-diff-mode

open patch-file

M-n

C-c C-a

I get "Hunk seriously messed up"


If I understand diff correctly, the patch aims for line 2204 = 
"(add-hook 'change-major-mode-hook..."

In my version of doc-view.el that line: "(add-hook 
'change-major-mode-hook..." is contained in line 2207.

That is probably the reason for "Hunk seriously messed up"

... So what I did is: I changed the source code of view-doc.el manually 
and not via the delevered patch. Then I tested it and ...
TADA!!! Success!!! It works.

Thanks for the effort

Heiner
