crecord: fix help bar display issue (issue5063)...
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.
