Hi,

I have received attached e-mail, which can not be displayed in Gnus (from
CVS) running in current CVS Emacs. The message

     fill-prefix too long for specified width

is shown. fill-column is 75 in my setup. Additional details on
request. I still have this article so I can test your changes.

Pou¾ívám FRITZ!X ISDN@2line USB (tzn, ¾e nemá MAC),  RH 7.2 a pppd 2.4.1.

Podle man (sekce MULTILINK)  pppd detekuje, ¾e øízená linka je pøipojena 
k tomu samému 'peerovi',  jako ji¾ existující linka dle shodného 'peers 
endpoint diskriminátoru' a vytvoøí vícenásobné spojení, tzv. 'multilink 
bundle'.

Mám funèní soubor parametrù "isp", volám jej pøíkazem 'pppd call 
isdn/isp', pøidám tam 'multilink' a posléze je¹tì 'endpoint IP:N.M.O.P', 
co¾ je ip pøidìlená rozhraní ppp0, popøípadì i 'endpoint phone:XYZ', co¾ 
je èíslo druhé linky. Spojení se ustanoví, ale multilink se nekoná, 
pakety nabíhají jen na ppp0, ppp1 si ani ne¹krtne.

Provider je Volný, multilink podporuje, pod Woknama to bì¾í O.K.

Máte nìkdo vyøe¹en multilink na USB zaøízení?
Díky.

Karel Babka

I'm not sure of myself but I think the value of `fill-prefix'
should be controlled by flow-fill.el, however it will be altered
by `fill-region-as-paragraph' if it isn't specified.  Here's a
patch for a tentative plan:

It must be a bug in my changes in fill.el.
I can't look at it just now, so I'll get back to you later,

I do not know where the bug is, but this change from Katsumi Yamaoka
<yamaoka@jpl.org> fixed this particular problem:

I'll have to convert to a program whose config files I can understand anyway
some day.

This indeed will prevent the buggy code from running.
But it doesn't fix the bug.  Of course, the patch might still be correct
for flow-fill.el, I don't know.
