[exim-dev] [patch-fixed] new option check_rfc2047_max_length

Option check_rfc2047_max_length switch on/off check length "Printed
Quotable" by RFC2047 (75 chars) in header decoding. Similar
to Outlook Express ingnored RFC, and ACL with regex contain localised
chars not work. This patch fix this.

Perhaps it is useful not only for me ;-)
