internal/scan: put -show <option> into single quotes

This establishes a convention where we wrap examples and mentions of
flag usage into single quotes to indicate proper usage. For instance,
this indicates that the verbose mode is triggered when both `-show`
and `verbose` are used at the same time one after another. The same goes
for other flags, such as scan.
