\n should be translated to \n\t\t\t or whatever number of tabs need to be used so as to properly align with the preceding line.

This is implemented via #160

Note that if you want a newline in your help string, use {n} and not \n

i.e.

.arg_from_usage("<some_arg> 'this is a really long help string that{n}I would like to have broken over two lines'")
