Suggested fix:
Output help information to stdout

sveta, you can try ./mysqlbackup --help > help.log 2>&1
The above command will output the result in help.log which is readable.

Hema, sure. But this still annoying and is not same as for other MySQL command line clients and other UNIX tools.

And output in help.log is actually readable. Problem is I need to use 2>&1 to use mysqlbackup --help | less for seeing help

Fixed in version 3.6.0
