facepalm -- how did I miss that `size() > 0`.  I'll fix that along with the next batch of updates.

Or another idea.  To get this out the door, perhaps I just drop this and `sanitizePath`?  The essential part (for me) is getting the `-dI` option working, and printing at least the `#include`s.  More useful diagnostic info can get tacked on later perhaps.
