Thanks resolved. (Re: Adding multipart indicator on summary line

[藤原 誠/ Makoto Fujiwara <makoto@ki.nu>]

Thanks everyone, now everything works fine.
The story was:

(1) I have modified my patch from originally sent wrongly
when adding following line.
+(eval-when-compile (require 'wl-folder))

The wrongly means, say, like this:
+    (if (stringp content-type)
+       (cond 
+        ((string-match "multipart/mixed" content-type) "@" "")
+        ((string-match "multipart/signed" content-type) "s" "")
+        ((string-match "multipart/encrypted" content-type) "e" "")
+        )) ))
+ 

I will add this patch to pkgsrc/wip/wl-current:
  http://pkgsrc-wip.sourceforge.net/
  http://pkgsrc-wip.cvs.sourceforge.net/viewvc/pkgsrc-wip/wip/wl-current/

Thanks again,

Add other indidators depending on types of multipart.

You will need following lines to utilize this change in 
your setup, for example, in ~/.wl.
