Named arguments in a single line "aligned"

[rbobillot]

With AlignParameters and AlignArguments on, when arguments or parameters are named on function call, even when they are all in the same line, if the first argument's name is shorter than the second, spaces are added between the name and the assignment, seemingly trying to "align" it with the second. As in

-   function(arg = 3, muchLongerArg = 13)
+   function(arg          = 3, muchLongerArg = 13)

I can't think of any situation where this behaviour can be desired.
