Can't delete last article in an nnml group

Can't delete last article in an nnml group

[Paul Stodghill]

Gnus v5.4.55 won't let me delete or move the last article in an nnml
folder. This happens even when the last article is not the only article in
the folder.

Do you have `nnmail-keep-last-article' set?

What is the value of `nnmail-keep-last-article'?

nnmail-keep-last-article's value is nil
  -- a variable declared in Lisp.

Documentation:
If non-nil, nnmail will never delete the last expired article in a directory.
You may need to set this variable if other programs are putting
new mail into folder numbers that Gnus has marked as expired.

Yes. To `t'. Reading the documentation for this variable, I'm not sure that
this should matter.

  nnmail-keep-last-article's value is t
    -- a variable declared in Lisp.

  Documentation:
  If non-nil, nnmail will never delete the last expired article in a directory.
  You may need to set this variable if other programs are putting
  new mail into folder numbers that Gnus has marked as expired.

The articles are not expired. It's simply the last (ie, highest numbered)
article in the folder that I want to `B DEL', make go bye-bye. Also, Gnus
is the only program writing messages to these folders.

Paul Stodghill isn't the first to be confused by this docstring.
Hopefully, the attached clarifies things.

(Is this really worth a changelog entry?  Lars, you're welcome to
discard it.)

Ah! I have been enlightened. Thanks to everyone who responded.
