mutate_if unexpected result when no columns match criteria #2009

mutate_if seems to apply an operation to all columns if none qualify:
> data_frame(a=1:2,b=3:4) %>% mutate_if(is.factor,as.character) %>% str
'data.frame': 2 obs. of 2 variables:
$ a: chr "1" "2"
$ b: chr "3" "4"

am I missing something?

My apologies, I just realized this was the same issue as #1989
