Change behaviour %k in gnus-summary-line-format?

[Svend Tollak Munkejord]

Hi,

With

(gnus-summary-line-format 
  "%U%R %(%[%10&user-date;: %-23,23f (%k)%]%B %s%)\n")

the size of the message is displayed due to the %k. If it is in the range
of 100k, I see "0.1M". 

Would it be possible to tell Gnus to display, say, "103k" instead, 1) making
it easier to read, and 2) increasing the number of significant digits by two?

(I use Gnus 5.10.2 and GNU Emacs 21.2).

Cheers,

(defsubst gnus-summary-line-message-size (head)
  "Return pretty-printed version of message size.
This function is intended to be used in
`gnus-summary-line-format-alist'."
  (let ((c (or (mail-header-chars head) -1)))
    (cond ((< c 0) "n/a") ;; chars not available
	  ((< c (* 1000))       (format "%db" c))
	  ((< c (* 1000 10))    (format "%1.1fk" (/ c 1024.0)))
	  ((< c (* 1000 1000))  (format "%dk" (/ c 1024.0)))
	  ((< c (* 1000 10000)) (format "%1.1fM" (/ c (* 1024.0 1024))))
	  (t (format "%dM" (/ c (* 1024.0 1024)))))))

This will print the numbers as "941b", "1.1k", " 86k", "102k", "472k",
"1.1M".  It seems that users have different preferences here: 100k or
0.1M?  900k or 0.9M?  Some people prefer the former
<news:8665yqqqlp.fsf@pille.fhaun.de>, some the latter
<news:r8hevize.fsf@hschmi22.userfqdn.rz-online.de>.

Is it useful to add another format specifier (say "K") or should we
leave it as an exercise for the user?

,----[ (info "(gnus)Summary Buffer Lines") ]
| `u'
|      User defined specifier.  The next character in the format string
|      should be a letter.  Gnus will call the function
|      `gnus-user-format-function-X', where X is the letter following
|      `%u'.  The function will be passed the current header as argument.
|      The function should return a string, which will be inserted into
|      the summary just like information from any other summary specifier.

Bye, Reiner.

That was nice. Thanks!

As implicit in my question, I support the former, since "0." takes up the
space of two characters without conveying information.
