apply: Don't unnecessarily update line lengths in the preimage

Browse source 
In match_fragment(), the line lengths in the preimage are updated
just before calling update_pre_post_images(). That is not
necessary, since update_pre_post_images() itself will
update the line lengths based on the buffer passed to it.
