Subject: [PATCH] [ruby/irb] Page the output in irb:rdbg sessions too
 (https://github.com/ruby/irb/pull/1043)

IRB started to page its evaluation output and it became a useful feature
for users. However, in `irb:rdbg` sessions, the output is not paged so
the sudden change in behavior is surprising and inconvenient.

This commit makes `irb:rdbg` sessions page the output of the debugger
too.
