When I pass a command with quotes to PtyProcess.spawn, it escapes the quotes, which causes my command to fail. The quotes are required and must not be escaped.

Here is code illustrating the problem:

from winpty import PtyProcess

cmd = 'cmd /c echo foo "bar" "baz"'
proc = PtyProcess.spawn(cmd)
data = proc.read(1024)
print(data)

Expected output:
foo "bar" "baz"

Actual output:
foo \"bar\" \"baz\"
