This better mirrors the behaviour of bash, for example:
$ if test -z = -z; then echo yes; else echo no; fi yes
This is parsed as a string comparison of "-z" and "-z", since the check for the binary "=" operator occurs first. Without this change, the command would be parsed as a -z test of "-", followed by a syntax error; a trailing -z without and operand.
This is a behavioural change, but I believe any commands affected were previously invalid or bizarely formed.

Applied to u-boot/master, thanks!
