Issue #252: beancount uses BASE/QUOTE inconsistently (blais/beancount)

New issue 252: beancount uses BASE/QUOTE inconsistently
https://bitbucket.org/blais/beancount/issues/252/beancount-uses-base-quote-inconsistently

Martin Michlmayr:

`bean-report foo commodities` shows me:

```
USD / UR
```

but when I use this pair as printed (with spaces) I get an error:

```
bean-report foo prices -c "USD / UR"
bean-report: error: Invalid commodity pair "USD / UR"; must be in BASE/QUOTE format
```

When I remove the spaces it works: "USD/UR"

Either `commodities` shouldn't print spaces or spaces should be accepted.
