generated Go causes staticcheck errors

[mcgaw]

error var _ should have name of the form errFoo (ST1012) and at least one file in a package should have a package comment (ST1000) are emitted by the staticcheck tool.

There is a long quite tedious discussion about the use of "exclude" in staticcheck, but wondering if this is something that could be quite simple to fix?

In the meantime I've added a staticcheck.conf file to the generated output dir, which includes the line checks = ["all", "-ST1012","-ST1000"], but that's less than ideal.

Staticcheck really shouldn't be flagging the blank identifier in ST1012; that's something I should fix.
