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.
crecord: fix typo in the help text
In the crecord help dialog, the toggle all option was wrongfully documented.
Instead of using 'a', one must use 'A' to toggle all the hunks. The crecord
header that is always displayed on the screen contains the right shortcut and
does not need to be changed.
