%c in gnus-summary-line-format in nnfolder groups

%c in gnus-summary-line-format in nnfolder groups

[Pavel Janik ml.]

Hello,

I'd like to have number of characters displayed insted of number of lines in
summary buffers so I changed

gnus-summary-line-format's value is 
"%U%R%z%I%(%[%4c: %-20,20n%]%) %s\n"

It works in nntp foreign groups but it does not work in nnfolder groups which
I use for mail groups (there is always 0 insted of the number of chars). Is it
normal? It is not mentioned in the docs.

Yes.  nnfolder articles normally do not have info on the number of
characters in the articles.

Can I workaround this? How? I'd like to have nr of chars there. The message
can have one line and 1GB+ of chars :-)

Does the following patch fix things maybe?  I created it to fix
something else, but am unsure whether it would fix your problem.  (Or
for that matter, break something else.)

I think this will give you the size of the head, not the body of the
message.

Perhaps, but the number is consistant with what NNTP NOVs give back,
which is why I wrote it that way.

Uhm -- the "char" field from NNTP is the size of the head of the
article?

`nnheader-parse-head' is narrowed to the article, not the head of the
article, in the instance I was tracing it.  (Specifically, when
caching an article.)  This may not be the case for the test you are
using.  I make no claims for this patch being the correct thing to do,
only for it working for the single instance I needed it for.
