Series.to_csv quotechar missing or to_csv wrong behaviour

See original GitHub issue

Code Sample, a copy-pastable example if possible

import pandas as pd
pd.Series(['x','x,x']).to_csv('my_file.txt', index=False)

The result of this code when you open the file my_file.txt is:

x
"x,x"

Expected Output

I think that either A) we decide that Series.to_csv doesn’t quote and the expected output is

x
x,x

or B) we decide that Series.to_csv quotes in the same way as DataFrame.to_csv in which case I would expect that Series.to_csv can take argument quotechar.

Would there be any interest in a to_string which accepts filenames? If not I guess we can have this closed. I wouldn’t mind implementing it.

Got it. So why does to_string only accept a buffer but to_csv accepts either a buffer or a filename path?
