Re: [PATCH 2/4] test-line-buffer: simplify command parsing

However, each case arm of the switch falls through to the
one below it. This is pointless (we know that a command
starting with 'b' does not need to check any of the commands
in the 'c' block), and it makes gcc's -Wimplicit-fallthrough
complain.

Wow, this is an embarassment. The code tries to cleverly optimize
it, and then fails miserably.

The updated one reads good.  Thanks.
