Dashes in double quoted arg detected as invalid args

[marekr]

Having an string arg

    m_argParser.add_argument( "--user-origin")
            .default_value( std::string() )
            .help( "User-specified output origin ex. 1x1in, 1x1inch, 25.4x25.4mm (default mm)" );

where the cli use is --user-origin="56.100000x27.000000mm" normally works fine.

1. --user-origin="-56.100000x27.000000mm" where a dash is introduced inside the string, triggers an invalid arg parse error

Changing the double quote to single quote --user-origin='-56.100000x27.000000mm' allows it to work

Examining the argv in msvc, the double quotes do get stripped out by Windows but the arg format of --user-origin= remains

while the single quotes remain

2. In the case of the single quote case, argparse then returns everything after the equals sign to the .get() function, including the single quotes which seems kind of odd as well.

I believe in python's argparse.

Doing --user-origin="-21242" is valid form and solution to --user-origin "-21242" not working usually

I don't have a Windows computer but does this work if you escape the double quotes?

--user-origin=\"-56.100000x27.000000mm\"
