If you have a complex bash configuration file which you want to keep,
source your .bashrc (or whatever you use) in compatibility mode
(the anonymous function will keep that mode local only for sourcing):

() {
	emulate -L sh
	setopt kshglob noshglob braceexpand nonomatch
	. ~/.bashrc
}

Most setups should work without any issues in this compatibility
mode, the most notable exception being [[ $var ]] which must be
cast into the more compatible [[ -n $var ]].
