I wonder why nobody using Emacs trunk or No Gnus complained about the
questions yet.  (I'll make it clearer what the question is all about.)

See <http://thread.gmane.org/gmane.emacs.gnus.general/66047/focus=66051>.
Summary: Before this change, stable versions of Gnus deleted delete
(intermediate) incoming mail files immediately after handling them
whereas development versions kept them forever.  After the recent
discussion, I've changed the default to keep the incoming file a
couple of days as a safety belt.

Sorry for that.  When I made this change, I completely forgot about
`mail-source-delete-old-incoming-confirm' (I've set it to nil ever
since I introduced it in 2003).

I agree that the default should be either...

(a) positive `mail-source-delete-incoming' and
    `mail-source-delete-old-incoming-confirm' set to nil, or...

(b) `mail-source-delete-incoming' set to t (as it was in Emacs <=
    22.1.91 / Gnus 5.10.8)

I will do that.

I'm sorry that this came up to late for pretest 22.1.92.  I'd suggest
to go for (a), i.e. keep `mail-source-delete-incoming' set to 2 and
set `mail-source-delete-old-incoming-confirm' nil (including the
improvements mentioned above).  Yidong, if you strongly prefer a
different change for 22.2, please let me know.

Bye, Reiner.
