[Reportbug-maint] Bug#790135: lists merged entries, but reponds "invalid" when trying to read them

[RadoQ]

Package: reportbug
Version: 6.6.3
Severity: important

While filing a report to "xserver-xorg-video-nouveau" it lists
#686611 as reported. But when I enter "m" or the entry number
directly "686611" for details it responds:

	"Invalid report number 686611"

I assume it's because 686611 is marked as merged with 595477, which
is also listed and does return details when asked for.
Either such entries shouldn't be listed or specially marked and
cross-referenced.

Thanks.
