Yes, actually I used Find.find in my example :-)  You're right about
the overzealous gsub'ing.  I'm not sure how directories were supposed
to be handled, but I thought I was ignoring them, which I accidentally
wasn't.  

But here's some rename weirdness I've discovered while doing this:

  $ ls u_score/
  u_file
  $ ruby -e 'File.rename("u_score/u_s", "u_score/u s")'
  -e:1:in `rename': No such file or directory - 
  u_score/u_s or u_score/u s (Errno::ENOENT)
	  from -e:1


I have to admit I have no idea why that happens or even what the error
exactly means.  (What's with the "or"?)
