Broken Build : Spaces in doc filename

A recently checked in doc change included a powerpoint file which has
spaces in its name.  This seems to be confusing the make implicit target
parsing for some reason.  This seems like a bug in our Make structure,
but for now, the easiest thing is simply to rename the file.
