The function has existed and raised an error since the "dawn of time"
(since CVS days), I guess I'm surprised this hasn't annoyed anyone else.
Basically it shadows `nnheader-report', and gives the server a single
chance to reconnect in case of failure -- the "nntp-with-open-group"
mechanism -- before failing altogether. All that's fine, I wish nnimap
had something similar, but raising the error seems wrong.
In fact raising the error would be the right thing in the code sketch I
posted above! This code is ahead of its time.
Anyway, simply removing the call to error should do the trick. That
will leave `nnheader-report' as the final form, which returns nil.
`nntp-report' is the final form everywhere it's called, so the nil goes
up to callers, which will (mostly) interpret that as failure.
