Rasql_Remove the additional break line for composite output

[Bang Pham Huu]

Create a collection and insert multiple MDD array to it, e.g:

rasql -q 'select sdom(c) from test2 as c' --out string
rasql: rasdaman query tool v1.0, rasdaman v9.5.0-beta1-g83e5ca18.
opening database RASBASE at localhost:7001...ok
Executing retrieval query...ok
Query result collection has 5 element(s):
  Result element 1: [0:100]
  Result element 2: [0:100]
  Result element 3: [0:100]
  Result element 4: [0:100]
  Result element 5: [0:100]

Then check the difference between 2 queries:

rasql -q 'select 1 from test2 as c' --out string
Query result collection has 5 element(s):
  Result element 1: 1
  Result element 2: 1
  Result element 3: 1
  Result element 4: 1
  Result element 5: 1

and

rasql -q 'select {1} from test2 as c' --out string (with additional breaklines)

Query result collection has 5 element(s):
  Result element 1: { 1 }

  Result element 2: { 1 }

  Result element 3: { 1 }

  Result element 4: { 1 }

  Result element 5: { 1 }
