go-guru--run has been split up to separate running the tool from turning its output into compilation-mode form. The definition command uses only the first part, and parses its output in JSON form. Added test, factoring the test script. Change-Id: I4c3e4a51a1346551a3703a5e3137c878d7b2d95f Reviewed-on: https://go-review.googlesource.com/19499 Reviewed-by: Michael Matloob <matloob@golang.org>
