comma-separated lists in nagios configs

Augeas Team,

We'd like to request the implementation of a useful feature: comma-separated lists in nagios config files (currently handled by nagioscfg.aug); for example,
```
key=val1,val2,...,valn
```
would be parsed into n subnodes in augeas' abstract syntax tree. Please let us know how likely (or how soon) this feature will be implemented.

Thanks for considering...
