> Affects Versions: 0.23.1, 0.24.0

> In {{adjustColumnWidths()}}, we set the member variable {{lineFormat}}, which
> is used by {{ProcessPath()}} to print directory entries. Owners and groups
> are formatted using the formatting conversion {{%-Xs}}, where X is the max
> length of the owner or group. However, when trying this with an S3 URL, I
> found that the owner and group were empty (""). This caused X to be 0, which
> means that the formatting conversion is set to {{%-0s}}. This caused a
> {{MissingFormatWidthException}} to be thrown when the formatting string was
> used in {{ProcessPath()}}.
> Formatting conversions are described here:
> http://docs.oracle.com/javase/1.6.0/docs/api/java/util/Formatter.html#intFlags
> The specific exception thrown (a subtype of {{IllegalFormatException}}) is
> described here:
> http://docs.oracle.com/javase/1.6.0/docs/api/java/util/MissingFormatWidthException.html
