[Scspamcop] Spammer trick to avoid reporting

I found some spam reported to SC doesn't parse well, sometime even impeding 
reporting to the mail source by SC.

Here is an example:

    http://www.spamcop.net/sc?id=z2232090009z22a228d65bcd0740402813c6f95a199az

(lines #7 and #8 are separated by CR, not by the CRLF sequence.

It seems to me that the effect of this trick is no report at all with QR, 
and report to only the mail source with manual reporting.

This seems to me a case common enough to be handed by the SC parser. I guess 
the SC parser parses header lines according to the (\n|\r\n?) regex sequence 
instead of only the Rfc-822 -defined one (\r\n), in order to cope with most 
submitting clients. But probably the SC parser should detect the message's 
overall delimiter sequence and then use only that one. This would void the 
effectiveness of this trick unless someone is manually submitting from an 
old Mac OS-9...
