Subject: fix logic bug in getthreadid
X-Git-Url: http://git.marmaro.de/?p=mmh;a=commitdiff_plain;h=b272c556cc930991994028c72ee487b38dada93c

fix logic bug in getthreadid

getthreadid now early exit the m_getfld2 loop, if the message-id _and_
the references field is found. Without this the wrong thread-id may
found if the message-id field is before the references field.
Thanks c_14 for reporting
