Comment:
I found the commit that fixed this:
55e7ab1210975e6276f3cab3ac0e1f35bcd772f0
{{{
Author: Gintautas Miliauskas <>
Date: Sun Jun 8 11:49:29 2014 +0000
Do not print the result of 'main' after invoking ':main' (fixes
#9086).
}}}
Since it has a test already, we don't have to do anything here.
Berdes: please have a look at that commit and [wiki:Building/RunningTests]
to see how the testsuite works.
