Subject: [mSQL] beta6: String addition bug, length gets wrong, fix included
Message-Id: <Pine.LNX.3.96.970423073034.20461A-100000@porkkana.hyvatti.iki.fi>

  This lite script:

$str1 = "ab";
printf ("str1:\"%s\" length=%d\n", $str1, #$str1);
$str2 = "a" + "b";
printf ("str2:\"%s\" length=%d\n", $str2, #$str2);

  ..produces this output:

str1:"ab" length=2
str2:"ab" length=1

  And the fix is here, though it leaves some miscalculated lengths in the
routine I leave the styling to someone who knows the code better:
