Inconsitent behaviour of `writedlm` with option `header=true`

[mauro3]

I expected that

writedlm("../products/mb@2500.csv", (rand(3,6), ["one" "two" "three"]), header=true)

would write a csv with header line one two three. Instead it writes a two line csv with rand(3,6)[:] as first and one two three as second line (i.e. being compatible with what readdlm does with the header option set).

Maybe the easiest fix would be to just change writedlm to only allow the quotes options, which seems to be the only one actually doing anything:

DelimitedFiles.jl/src/DelimitedFiles.jl

Lines 781 to 786 in db79c84

	function writedlm(io::IO, itr, dlm; opts...)
	optsd = val_opts(opts)
	quotes = get(optsd, :quotes, true)
	pb = PipeBuffer()
	for row in itr
	writedlm_row(pb, row, dlm, quotes)
