Are these being detected with 3rd party signatures?

Try -n

eg.

echo -n This is a text line from the annoying spam|sigtool --hex-dump
5468697320697320612074657874206c696e652066726f6d2074686520616e6e6f79696e67207370616d

echo This is a text line from the annoying spam|sigtool --hex-dump
5468697320697320612074657874206c696e652066726f6d2074686520616e6e6f79696e67207370616d0d0a

Note that line feed 0d0a etc. at the end of the signature, which may
cause it to fail.
