Arguments don't support spaces.

[fitzy101]

When defining arguments for the command, the arguments are automatically split into an array, for passing into the Exec function. This will then call the command with the args separately in the shell. I want the ability to quote an argument, so it can be executed as a whole argument instead of being split up. e.g.

cmd -a 'my argument for the flag'

instead of
cmd -a my argument for the flag
