Bug #4981: 4.x and 5.x produce non-optimal execution path,
3.23 regression test failure
The member SEL_ARG::min_flag was not initialized,
due to which the condition for no GEOM_FLAG in function
key_or did not choose "Range checked for each record" as
the correct access method.
mysql-test/r/select.result:
testcase for 'Range checked' access method
mysql-test/t/select.test:
testcase for 'Range checked' access method
sql/opt_range.cc:
All of the class members initialized
