bug#32129: 26.1; Bug in add-dir-local-variable when used with eval, prog

Subject: bug#32129: 26.1; Bug in add-dir-local-variable when used with eval, progn and setenv
Date: Thu, 12 Jul 2018 01:18:19 +0200

I'm sorry for the noise, I just retried it and it worked, TEST was set. So the 
generated .dir-locals.el does the right thing.

Anyway: Shouldn't the .dir-locals.el look different? This is of course just a 
question of preference, if it makes the code more elegant or something I would 
accept that it's better to leave it as it is.

Best regards,
Luis
