Description

When a view function, like the reduce one, is an empty string, like in:

"by_type": {
       "map": "function (doc) {\n    if (doc.type) {\n        emit(doc.org, doc);\n    }\n}",
       "reduce": ""
   } 

the message shown in a message box and the logs is

"missing function"

; while this is correct, it is not terribly useful to the user, something like:

"function 'by_type: reduce' is not defined"

would lead to quicker debugging.
