(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 summary just like information from any other summary specifier.
