Display groups in Group buffer with >0 cached messages?

Display groups in Group buffer with >0 cached messages?

[Kai Großjohann]

Is there any way to tell Gnus that a group which has cached messages
should always be shown in the Group buffer?  (This already works for
ticked messages, but I can't use ticked messages.  Reason provided on
request.)

There is no pre-defined functionality in Gnus for doing this.

Although I guess you could run `gnus-summary-limit-include-cached'
from one of the late summary buffer entry hooks.

I don't think Kai wants this.  I guess it should be called like
gnus-group-list-cached.

I also want such a function so that I can find an ancient cached
message more efficiently.

Oh, right.  Hm.  Well, I don't think that would be difficult to
implement -- one would just have to iterate over all the groups and
pick out the ones that have cached articles in them.

*time passes*

Looking over `gnus-group-prepare-flat', Gnus chooses to display groups 
based on a predicate in there.  Perhaps we could add an extra
parameter to that function (and friends) that would allow a different
predicate, which would make it really easy to implement all kinds of
different selection criteria?

I just implemented one, called gnus-group-list-cached and
gnus-group-prepare-flat-predicate. 'A c' is the key sequence.
