Description

I was paging through a large array and hit ctrl-c.

I was expecting to go back to the irb session.

I got an error

    @dorianmariefr Thanks for reporting. Does this always happen when you Ctrl-c in a pager, or intermittently, or only when paging certain content? Asking because I can't reproduce it myself, so more information will help a lot.

    Reproduced by

    irb(main):001> 20000.times.to_a

    then type \C-c and q

    with PAGER=less less --version #=> less 581.2 (POSIX regular expressions)
    To reproduce, the output bytes passed to pager should be large enough. (>= 72*1024+1 bytes in my environment)
    Maybe related to pager's read buffer size, I guess.
