Feature Request: detect & suggest (os.File).Write([]byte("normal looking string")) -> (os.File).WriteString("normal looking string")

[cwedgwood]

I noticed in a few local code bases here frequent use of a pattern along the lines of:

var f os.File
f.Write([]byte("# do not edit\n"))

and wonder if in some (not all) circumstances we can determine if these strings either as constants or by use are essentially human readable in which case we could have:

var f os.File
f.WriteString("# do not edit\n")

(Internally WriteString uses unsafe to avoid allocation and copy)
