From ea009d4743ab4b801703982086e053e74266ff4c Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Sat, 23 Mar 2013 23:50:28 +0000 Subject: hashtable: preparations to use hexport_r() for "env grep" The output of "env grep" is unsorted, and printing is done by a private implementation to parse the hash table. We have all the needed code in place in hexport_r() alsready, so let's use this instead. Here we prepare the code for this, without any functional changes yet.
