[gnu.bash.bug] precedence of -a over -o in bash-0.99 test

andy@CSVAX.CALTECH.EDU (Andy Fyfe) (06/14/89)

    bash$ if [ x -o y -a "" ]; then echo yes; else echo no; fi
    no
    bash$ enable -n [
    bash$ if [ x -o y -a "" ]; then echo yes; else echo no; fi
    yes

test(1) is advertised as giving precedence to -a over -o.  Bash should
do the same.
