[ic] Strange whitespace

[DB]

I think this mysterious whitespace is why my query is failing. The below 
code displays

| BS | instead of the expected |BS|

I can't tell where these spaces are coming from and I can't get rid of 
them. I use the pipe characters to make spaces easier to spot.

[tmp ol_sku_test]BS-12345[/tmp]

[tmp sku_prefix2]
[perl]
my $ol_sku_test = "[scratch ol_sku_test]";
my @sku_array = split('-', $ol_sku_test);
return "@sku_array[0]";
[/perl]
[/tmp]

|[scratch sku_prefix2]|

Any thoughts are welcome!
