Bug description

The Arg.align function allows to correctly align docstrings of the form

-foo FOO My docstring for foo
-bar BAR My docstring for bar

by using the docstring "FOO My docstring for foo" in the first case and "BAR My docstring for bar" in the second case.

Unfortunately this does not allow to document Tuple arguments which have more than argument component, e.g.

-tuple FOO BAR My docstring for foo

In other words, it would be nice to be able to somehow include spaces in the "first word" of the docstring.

I am not sure what a good solution would be that would not break backwards compatibilty.

Maybe we could declare a not-very-common character to be rendered as a space when found in the "first word" of the docstring.

Mantis stripped the spaces from my description; several spaces are supposed to be present before "My docstring..." in each case.
