Individuals w/ no middle names cause blanks

Empty middle initials seem to become part of customer names. 

For example, suppose I have a customer record individual name "John Doe" with first name "John" and last name "Doe".  We have auto numbering ID's for our customer records, so assume for the moment that this is ID# C1234.  The name that is built to go with this ID is not "C1234 John Doe" as one would expect, but actually "C1234 John  Doe" (with two spaces between first and last name; the second space may not be evident as the HTML rendering makes one invisible). 

It seems like the empty middle name (which I've verified in the UI is indeed empty) none-the-less generates an additional space in the name.  This isn't simply a GUI issue either; when exporting CSV/XLS from the UI, the additional spaces are present.
