That would work, other than for people who had filenames with %20 in 
it... My browser saves html files with %20 instead of space characters, 
so if I ran make on some html files it might untokenize and not be able 
to access the actual file.

... and then what if I have both a genuine space and a %20 filename in 
the same directory..? I think it must be done with a character which 
will never occur in a standard filename.

Or, rather than the relatively short, (and also common %20), we could 
use a token which will not likely occur, like a 256bit unique number. 
(..and pick a different 256bit unique number should the default 256bit 
unique number show-up in a filename at run-time!).
