BASH_COMMAND

[Brian J. Murrell]

Is there something I am mis-understanding about $BASH_COMMAND?  The
manpage says:

       BASH_COMMAND
              The command currently being executed or about  to  be  executed,
              unless the shell is executing a command as the result of a trap,
              in which case it is the command executing at  the  time  of  the
              trap.

However:

$ trap 'echo $BASH_COMMAND' ERR
$ false
echo $BASH_COMMAND

So, in the trap, $BASH_COMMAND seems to contain the line command being
executed in the trap.  I would have expected to see:

$ trap 'echo $BASH_COMMAND' ERR
$ false
false

given the explanation in the manpage.

I must be misunderstanding something.
