From: Ilya Bobyr <ilya.bobyr@xxxxxxxxx>
It is not very likely that any of the "*=?!" Characters would be useful
in the argument short or long names. On the other hand, there are
already argument hints that contain the "=" sign. It used to be
impossible to include any of the "*=?!" signs in the arguments hints
before.
Added test case with equals sign in the argument hint and updated the
test to perform all the operations in test_expect_success matching the
t\README requirements and allowing commands like
./t1502-rev-parse-parseopt.sh --run=1-2
to stop at the test case 2 without any further modification of the test
state area.
