Bug #30358 mysqlimport seems to implicitly enable --ignore when --local is used

Description:
mysqlimport behaves differently with --local than without.
The flag (or at least one of them) that behaves different is the --ignore option, see below:

How to repeat:
# Cut and paste friendly script
mysql -e "CREATE DATABASE IF NOT EXISTS test"
mysql -e "CREATE TABLE bugtest ( a INT PRIMARY KEY ) ENGINE = MyISAM" test
mysql -e "INSERT INTO bugtest VALUES (1)" test
echo "1" > /tmp/bugtest.csv
mysql -e "SELECT * INTO OUTFILE 'bugtest.csv' FROM bugtest" test
mysqlimport test bugtest.csv
#mysqlimport: Error: Duplicate entry '1' for key 1, when using table: bugtest
mysqlimport --local test /tmp/bugtest.csv
#test.bugtest: Records: 1  Deleted: 0  Skipped: 1  Warnings: 0
rm /tmp/bugtest.csv 
# Also have to delete the bugtest.csv in $DATADIR/test
# Note that even if you run this last one with --help it doesn't show ignore as TRUE

says:

With LOCAL, the default behavior is the same as if IGNORE is specified; this is because the server has no way to stop transmission of the file in the middle of the operation.
So, the original submission is !Bg

However, the --help output should still show that ignore is set to TRUE if local is set.

flupps@flupps:~$ mysqlimport --local --help
...
ignore                            FALSE
...

Thank you for the report.
