When test-parse-options detects an error on the command line, it gives the usage string just like any parse-options API users do, without showing any "variable dump". An exception is the callback test, where a "variable dump" for the option is done before the command line options are fully parsed. Do not expose this implementation detail by separating the handling of callback test into two phases, one to capture the fact that an option was given during the option parsing phase, and the other to show that fact as a part of normal "variable dump". The effect of this fix is seen in the patch to t/t0040 where it tried "test-parse-options --no-length" where "--length" is a callback that does not take a negative form.
