[arch-general] /etc/bash.bashrc not sourcing/setting HISTXXX environment

   I generally create a system-wide /etc/bash.bashrc.local file to contain 
history defaults. E.g.:

$ cat /etc/bash.bashrc.local
HISTIGNORE='[ ]*:&:?'

   (HISTSIZE & HISTFILESIZE are exported on a per-user basis in ~/.bashrc) I 
then just add a line to source it in /etc/bash.bashrc:

$ cat /etc/bash.bashrc
# /etc/bash.bashrc
# - source /etc/bash.bashrc.local
[ -r /etc/bash.bashrc.local ] && . /etc/bash.bashrc.local

   Both files are present and readable:

$ ls -l /etc/bash.bashrc*
-rw-r--r-- 1 root root 697 Apr  6 20:01 /etc/bash.bashrc
-rw-r--r-- 1 root root 418 Mar 10 09:40 /etc/bash.bashrc.local

   I do this the same way on both Arch and SuSE. Chasing a bash bug on SuSE, I 
would check the the environment with:

$ env | grep HIST
HISTIGNORE= *:&:?:??

   Doing a pacman update earlier to day, I just checked the environment on Arch 
on a whim:

$ env | grep HIST

   Huh? Where is HISTIGNORE and HISTCONTROL? Is there something unique to Arch 
that prevents sourcing or prevents setting HISTXXX in this manner. I can't think 
of anything offhand that would prevent it, but it certainly isn't being set. Any 
ideas on why?
