Fix bogus list-iteration code in pg_regress.c, affecting ecpg tests only.
While looking at a recent buildfarm failure in the ecpg tests, I wondered why the pg_regress output claimed the stderr part of the test failed, when the regression diffs were clearly for the stdout part. Looking into it, the reason is that pg_regress.c's logic for iterating over three parallel lists is wrong, and has been wrong since it was written: it advances the "tag" pointer at a different place in the loop than the other two pointers. Fix that.
