vm-previous-message regression in mbox mode

[sujith_m82]

In summary mode, sometimes the message is not fontified, i.e., the colors are absent, when using vm-previous-message (keymapping: "p").
Moving to the next message and then back to the previous one fixes it, and the message is now colorized properly. This behaviour is random, but easily reproducible. This issue was not seen when I used the 8.0.x releases ...

My Emacs version: GNU Emacs 23.2.1
VM: 8.1.93a ( I tried with trunk too, the issue is sill present )

I have this in my .emacs:

(add-hook 'vm-summary-mode-hook 'u-vm-color-summary-mode)
(add-hook 'vm-select-message-hook 'u-vm-color-fontify-buffer)
(defadvice vm-decode-mime-message (after u-vm-color activate)
  (u-vm-color-fontify-buffer-even-more))

u-vm-color is a user-contributed library and it is not being
maintained by any one.

However, vm now has vm-summary-faces library integrated into it. So,
there is no need to use u-vm-color for the summary. Please see the
NEWS file and the info manual.

The Summary list is fine, the Presentation buffer for the mail is not being updated properly.
I used vm-summary-faces instead of u-vm-color and the summary is colorized, but the message is not - am I missing something here ?
u-vm-color provides a bunch of faces to tweak ( author, date, recipient, subject, signature ... ), is this provided by VM now ?
Or is there an alternate way to manipulate message faces in the Presentation window ?

Sorry for asking all these questions in the bug report, but digging into the info doc didn't turn up anything. :(

No, vm-summary-faces only colors the summary. VM doesn't have any
in-built stuff for coloring the message presentation, other than
headers and URL's.

Not that I know of. If you can use u-vm-color for the message bodies
without using its summary fontification, then please do. If it is
still broken when you try it, I can take a look at it, but I can't
promise that it will be fixed. (That is the point of saying that
u-vm-color is not "maintained".)

Ok, thanks for the explanation.

[sujith_m82 (m-sujith)]

Ok, I found some time to take a look at this and adding this to my .emacs fixes the issue:

(defadvice vm-show-current-message (after u-vm-color activate)
   (u-vm-color-fontify-buffer-even-more))

The earlier advice for "vm-decode-mime-message" was not being invoked for us-ascii messages, which is why
the fontification wasn't being done.

Hi Sujith, Thanks for the fix and sorry for the delay in getting back.

I have added a comment in the preamble of u-vm-color.el.

Cheers,
