tg.sh: Unnecessary newlines in the first generated test

When generating tests, the first generated test contains unnecessary newlines before the contents of each file. Given a testfile with the following first case:

0=

0

The test input t0.in is generated with a single newline before the specified input:

0=

And the test output t0.out is generated with two newlines before the specified output:

In most cases this will cause the test to fail due to whitespace discrepancy. I believe the issue has something to do with the generation of the array when reading the testfile expressed in this chunk of code:

i=0
s=1
declare -a tests

KEY=$RANDOM
sed '/^ *#/ d' < ${TESTFILE} > /tmp/tmp-$KEY.txt

while read -r line; do
  # If we find an empty line, then we increase the counter (i), 
  # set the flag (s) to one, and skip to the next line
  [[ $line == "" ]] && ((i++)) && s=1 && continue

  # If the flag (s) is zero, then we are not in a new line of the block
  # so we set the value of the array to be the previous value concatenated
  # with the current line
  [[ $s == 0 ]] && tests[$i]="${tests[$i]}"$'\n'"$line" || { 
    # Otherwise we are in the first line of the block, so we set the value
    # of the array to the current line, and then we reset the flag (s) to zero 
    tests[$i]="$line"
    s=0
  }
done < /tmp/tmp-$KEY.txt

rm /tmp/tmp-$KEY.txt
