Does POV make sure it hasn't already included a particular include?  I think
not, or a lot of the include file style functions wouldn't work multiple
times.  Parsing a long include of essentially just definitions (even if they
overwrite only themselves) could take quite a bit of time, if it's a long
file.

So there is some use in checking to see if a particular include (not of the
type where including multiple times can have different results) has already
been included.
