DatabaseMetaData.getVersionColumns BUFFER_LENGTH column

[Mark Rotteveel]

I'm currently implementing DatabaseMetaData.getVersionColumns for 
Jaybird, and I noticed that this defines the BUFFER_LENGTH column as 
"length of column value in bytes", while all other metadata methods that 
include BUFFER_LENGTH specify "is not used".

Is BUFFER_LENGTH really intended to be implemented for 
getVersionColumns, or is just leaving it null good enough? And if so, 
should the API documentation be amended?
