Code review comment for lp:~percona-dev/percona-xtrabackup/bug_737462

Valentine,

1. $option_ibbackup_binary is initialized to 'autodetect', so the condition (!$option_ibbackup_binary) will never be true. You should use "if( $option_ibbackup_binary eq 'autodetect' ) " instead.

2. Alignment and closing brace placement is wrong.

3. I think it makes more sense to default to 'xtrabackup' rather than 'xtrabackup_51'. Then, in the windows case, for example, you don't even need to specify the binary explicitly.

I think it's easier to show the patch:
