Comment 1:

I think the command is working as intended. Just like 'install myfile /dev/null' would
have the same effect.
You should arrange for that command to not be called.

Comment 2:

That command is part of the all.bash test suite. So while the issue may be misnamed
(change to "doc: codewalk test invokes go build with -o /dev/null"), it still exists.
The file in question is $GOROOT/doc/codewalk/run from this CL:
