At least on the go list driver, which is the default fallback. Note that
we need to call 'go list' on Load("foo") and Load(), but not
Load("name=bar"). This is what the current logic was trying to
accomplish.
But it didn't take into account the case where there are zero initial
patterns, in which case we should still call 'go list'. Fix that, and
add a test.
Fixes#28767.

it was infeasible, so no 1.10.x versions will support the non-fallback

Previously, if `packages.Load` failed, it would (sometimes? always?) return an error + no initial packages.
The moved `len(initial)` check was overriding the actual err with a much less useful one.
Example output before:
```

And after:

This is because it assumed that the user hadn't set their own GOCACHE,
and thus that all source files in the cache would be under the default
"go-build" cache directory.
We could fix this via os.Getenv("GOCACHE"), but a simpler mechanism is
to see if the source file has an extension. Source files don't have an
extension in GOCACHE, so that's much simpler to detect.
After this change:
$ GOCACHE=$HOME/go/cache go test

Now that we support checking for duplicate struct field tags across
anonymous struct fields, we must deal with the fact that the files
involved in such a warning may not be in the same package or directory.
This could lead to errors where a file was mentioned in a package where
it didn't exist. Or even worse, point at a location within an existing
file that doesn't contain the field we want, causing even further
confusion to the user.
To fix this, always make the "also at" positions relative to the current
warning, if possible.

The first issue is that %b and %o can print pointers, but printVerbs
didn't reflect that:
The %b, %d, %o, %x and %X verbs also work with pointers,
formatting the value exactly as if it were an integer.
The second issue is that arrays can never be printed as pointers. This
was previously reported as part of #27672.
The third issue is that only %p can print all slices, maps, and
functions as if they were pointers. This differs from verbs like %b or
%o, which can't print these types as pointers.
Fix all of the issues above, and add extensive test cases covering all
the combinations. Verified all of them with an executed program. The
amount of test cases is perhaps overkill, but this is not the first time
we've gotten the printf pointer logic wrong.

This allows us to more easily route parameters to the driver and add
more parameters without breaking users. The driver doesn't need to
have the same interface as go list, because it's unlikely the driver interface
will converge with the go list interface.
We still pass in the query "words" to the driver in the argv, because
that's as good a place as any, but there's no "list" command.
Question: should we add a "command" option to the driverRequest struct?
