But that doesn't explain why the spaces are removed and I can't find
anywhere in the documentation of readline that explains it.  I would
have to study the code itself to know why.

Because nobody wants empty arguments to deal with, but it's useful to
know where readline splits the words when it finds the word it wants to
be completed.
