"Set the scope for the Go guru, prompting the user to edit the previous scope.
The scope specifies a set of arguments, separated by spaces.
It may be:
1) a set of packages whose main functions will be analyzed.
2) a list of *.go filenames; they will treated like as a single
package (see #3).
3) a single package whose main function and/or Test* functions
will be analyzed.
The scope restricts analysis to the specified packages.
Its value is a comma-separated list of patterns of these forms:
golang.org/x/tools/cmd/guru # a single package
golang.org/x/tools/... # all packages beneath dir
... # the entire workspace.
In the common case, this is similar to the argument(s) you would
specify to 'go build'."
A pattern preceded by '-' is negative, so the scope
encoding/...,-encoding/xml
matches all encoding packages except encoding/xml."
