[exim] Result repeated and contains a newline character ?

Hi,

I am trying to figure out why my result is 1) being repeated and 2)
contains a newline character?

Surely the result should just be "0", not "0\n0"? What am I doing
wrong?

My condition in my exim configure file:

    2004   condition             = ${if and {\
    2005                                                     { or  
{ { !eq {$header_X-Trend:}{clean} }\
    2006                                                               
{ !eq {$header_X-ClamAV:}{clean} }\
    2007                                                            }\
    2008                                                     }\
    2009                                                     {< {${sg 
{$header_X-Spammark:}{\N(\d+)\.(\d+)\N}{\$1}}}  
{$ACL_SPAMMARK_THRESH} } \
    2010                                                     {match{$ 
{extract{1}{\:}{$ACL_SPAMMARK_FLAGS}}}{vINS}}\
    2011                                                   }\
    2012                                       }

Can anyone also please confirm if it's normal to print the result and
a newline when testing with "-be"?

# exim -be < bar
> 100
>
# cat bar
${sg{100.00}{\N(\d+)\.(\d+)\N}{\$1}}

regards,
Jaco
