[Reportbug-maint] Bug#849763: reportbug: aborts if you attempt to read "Common issues with reportbug:"

[Adam Borowski]

Package: reportbug
Version: 7.1.1
Severity: normal

Hi!
When trying to "reportbug reportbug", it displays a piece of text starting
with "Common issues with reportbug:".  The only way to continue I found is
to press 'q' immediately; any other keypress, such as scrolling, etc, that
can be used to read the rest of the text will appear to work, but once the
pager is finally done, reportbug will ask the next question:

.----
Briefly describe the problem (max. 100 characters allowed). This will be the bug email subject, so keep
the summary as concise as possible, for example: "fails to send email" or "does not start with -q option
specified" (enter Ctrl+c to exit reportbug without reporting a bug).
`----
and when I type anything and confirm with Enter,
.----
reportbug: exiting due to user interrupt.
`----


Meow!
