Subject: sed(): Don't call enforce_header_order() if a filter removed the request line
X-Git-Tag: v_3_0_30~147
X-Git-Url: http://www.privoxy.org/gitweb/?p=privoxy.git;a=commitdiff_plain;h=ff3493f08f35e907620bc9d56ba202d7e1300a68;hp=8aad4aff233360830511c104c2e6183b4a35d5b4

sed(): Don't call enforce_header_order() if a filter removed the request line

... as enforce_header_order() asserts that the request line is present.

Without the request line the request will be rejected as invalid
later on anyway, so sorting the headers first is pointless.
