has_content

[hadley]

Boolean if there's any content associated with request. as = "auto" should throw an error.

Here's current definition of has_content():

has_content <- function(x) {
  length(x) == 0
}

I'm trying to use it over in my PR re: devtools and ... any chance you meant this to involve content(x) instead of x and/or to test if length is greater than zero? I can't find any usage of has_content() any where on github, so I can't figure out if I'm just missing something ... but this seems really weird.

Hmmm seems like it should be length(x$content) > 0 :/
