Note that there are only such `nil`s when the evaluation of the
interactive spec returned them. It's somewhat consistent if the command
history includes the argument list exactly as returned by `interactive'.
The more general problem is to provide interactive forms that work
nicely with `repeat-complex-command' - something programmers are often
not aware of when writing commands.
Anyway, trying of prettify away those `nil`s seems like overkill to me.
In theory even an optional `nil' can be significant.
Michael.
