Use `if..then` in `show` to avoid non-zero exits. 

The `[[ ... ]] && ...` conditional style results in non-zero exits when
the test is false. Moving this to a traditional `if..then` style avoids
this behavior while also being more explicit about the objective of the
code. `|| return 0` or `|| exit 0` could have been added as an
alternative way to avoid the non-zero exit behavior, but is not used in
this case because the traditional `if..then` style is more common.
