Touch up string expansion. (#4344)

Browse Source 
* Touch up string expansion.

I'm chasing this:

```
$ (module purge; spack install perl %gcc/5.4.0)
==> Error: No installed spec matches the hash: '%s'
```

There's something deeper going on, but the error message isn't helpful.

After this change it tells me this:

```
$ (module purge; spack install perl %gcc/5.4.0)
==> Error: No installed spec matches the hash: '5.4.0'
```

Which is weird because `5.4.0` is not a hash...  Whatever is going on here, the error message needs to be fixed.
