bad variable name

[Inspired]

This same error was reported here https://bugs.launchpad.net/bugs/1202940. However, this is a over 4 years later, so I am submitting a fresh report.

The script ends with the following error:

/mysql_scripts/tuning-primer.sh: 401: local: 2097152: bad variable name

right after outputting the header for the JOIN section.

mysql -v provides:

Your MariaDB connection id is 15324930
Server version: 10.1.26-MariaDB-0+deb9u1 Debian 9.1

Is it not possible for the script to do some fault handling / testing with regard to which `join_buffer` variation to use, depending on the MySQL environment?

Trying to debug I could get rid of the error by replacing as so on line 943 :

- mysql_variable \'join_buffer%\' join_buffer_size
+ mysql_variable \'join_buffer_size\' join_buffer_size

I'm not sure why '%' was used here, but it seems to work.

Older versions of MySQL (<4.0) named the variable simply join_buffer. The
% was a compatibility requirement.
