Re: [PATCH] test-lib: check Bash version for '-x' without using shell arrays

Would it perhaps be simpler to just hide the syntax behind eval? Like

 		if test -z "$test_untraceable" || {
 		     test -n "$BASH_VERSION" && eval '

			 test ${BASH_VERSINFO[0]} -eq 4 &&
			 test ${BASH_VERSINFO[1]} -ge 1
		       }
 		     '

It indeed is somewhat easier to see that your version does exactly
the same as the original than the posted patch, but the pattern
substitutions are not all that bad, either.
