crecord: fix help bar display issue (issue5063)

Before this patch, the help bar in crecord wouldn't be printed correctly when
the terminal window didn't have enough column to display it. This patch adds
logic to make sure that the help bar message is always displayed. We use an
ellipsis when it is not possible to display the complete message.
