191 * quotation mark, one backslash is placed in the argv array
192 * for every pair of backslashes, and the double quotation
193 * mark is interpreted as a string delimiter.

195 * quotation mark, one backslash is placed in the argv array
196 * for every pair of backslashes, and the double quotation
197 * mark is "escaped" by the remaining backslash, causing a
198 * literal double quotation mark (") to be placed in argv.
