Removing Agent category

[Rade Markovic <markovicr@softhome.net>]

I don't know if this is a bug, but here's the description.

The content of my ~/News/agent/lib/categories file is:

((default (not low) file nil))

`J c'
`a'
newcat RET

and now, the content of the file above is:

((newcat false nil nil) (default (not low) file nil))

What's been bothering me is the fact that after killing the newly
created category with `k', the category `newcat' disappears from
the category buffer, but only temporarily, because
~/News/agent/lib/categories doesn't get updated after `k'. After
restarting Gnus, the killed category still exists in the category
buffer.

Well, after some further experimenting, I noticed that if I add n new
categories, then I'm able to kill n-1 out of them and
~/News/agent/lib/categories file is updated. It's just killin' the
n-th one. Bizarre.

Happy New Year to All
