Hi Hackers,
This patch fixes a trivial bug where an extra whitespace was added
when dumping an array, for example:
```
:sort.numCols 2
:sort.sortColIdx ( 1 4)
:sort.sortOperators ( 97 1754)
:sort.collations ( 0 0)
:sort.nullsFirst ( false false)
```
The unnecessary whitespace is now removed.
Regard regards,
