test ... -a ...
is not portable (POSIX permits non-XSI systems to omit support for these
operators, but even where they are supported, there are some inherently
ambiguous inputs where you CANNOT predict whether the shell will parse
-a as a binary operator or as an argument to some other operator).
Instead, you should ALWAYS break dual tests into:
test ... && test ...
instead. (Same for '-o' vs '|| test')
