Remembers the path this arg was given, on the parser that parsed it.
The path can't just be read back out of the parsed namespace once parsing finishes: another arg sharing this one's dest could have put a value there, from a config file or anywhere else, and writing a config file overwrites the path it is given. Recording it as the arg is parsed means only this arg decides where that write goes.
add_argument() puts this over whichever store action the program asked for, so an arg that does something of its own with the path still records it.
