slrn does not filter on content-transfer-encoding

[Thomas Kenig]

The following line in the Score file does not work for slrn:

[*]
Score: =-9999
%Expires:
Content-Transfer-Encoding: base64
%EOS

Running slrn with debugging reveals

>XHDR Content-Transfer-Encodi 325085-325085
>^M

<221 Header information for Content-Transfer-Encodi follows (from articles)^M
<.^M
>XOVER 325092-325100

which indicates that the header name is truncated.

Setting

#define MAX_KEYWORD_LEN 32

seems to fix it.
