Thanks Paul, I understand, just asking myself if changing this in the backend would really break something? Understand it looks nicer in owget - but anywhere else it is programatically just annoying..
I guess any client/function has to implement some parser for removing the leading whitespaces to get the value so it won't break much - although I might oversee something(?) But at least in owhttpd/text/Json they are useless overhead IMHO. In owget in breaks using it with simple (Ba)sh like let without working around the leading spaces first etc.pp. Lets hear other thoughts on this..
