From 01c799579c9d64d32016fa6127a74e2d864fd9a9 Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Sun, 1 Feb 2015 16:47:39 +0000 Subject: The function rew_sub() tries to rewind any all all kinds of blocks and elements under any and all circumstances, even handling some bad block nesting now and then. Little surprisingly, this ends up in excessive complexity and has caused many bugs in the past. Start to slowly disentangle this mess by replacing calls to rew_sub() immediately following mdoc_head_alloc() by the much simpler rew_last(). Gets rid of the first two rew_sub() calls out of twenty.
