Seems to work here too, thank you. But we should probably keep the "file 
not found" reporting (-u means etags's output is unused anyway). It will 
help when the file name is actually a typo.

I wonder if 'make tags' would be able to make use of it somehow. If not, 
I'll probably have to reimplement it in Elisp anyway. Eli, any thoughts?
