Hey guys,  
I noticed this constraint on agg names

> <https://github.com/elastic/elasticsearch/commit/f1248e58>

  
It's not mentioned in the guide or under breaking changes for 1.1.0  
(instead the breaking change is buried in the issue, which is an  
enhancement)

It seems to me the most convenient name for a terms agg is the field name  
itself, which very often contains the now non permited character '.'
