The editing flags specify a sequence of editing operations.

The -fmt flag reformats the go.mod file without making other changes.
This reformatting is also implied by any other modifications that use or
rewrite the go.mod file. The only time this flag is needed is if no other
flags are specified, as in 'go mod edit -fmt'.

The -module flag changes the module's path (the go.mod file's module line).
