    bashrc: Change =~ test to globs. Fixes mkshrc.
    
    mksh shares bash.bashrc and [[ $TERM =~ xterm* ]] causes syntax error on Leap15 and TW;
    mksh: /etc/mkshrc[140]: syntax error: unexpected operator/operand '=~'
    
    Unless this fuzzy equal plus glob has another purpose, I see no reason to use it. All shells that share this file seem to support double globs in a dual bracket test
