I don't think we care enough about performance of most of the scanners
to make them all backup-free, so -1 to that idea.
We could possibly replace the command line switches with %option
entries in the files themselves. But I think the reason we haven't
done so for -b is that the Makefile still needs to know about it
so as to know what to do with the lex.backup output file.
