workspaces tutorial query

[Dan Kortschak]

I was just taking a look at the workspaces tutorial and saw that while
the doc says that adding the local example module will result in

go 1.18

use (
./hello
./example
)

what actually results is

go 1.18

use (
./hello
example
)

The behaviour is otherwise as expected, but this may confuse some
readers given that leading dots are important in other paths used by
the build system.

Should the doc be updated or is the tool's behaviour unexpected here?

thanks
Dan
