How do you plan to handle these cases?

```
%files
'/foo'\''bar' # single quotes
'/foo'bar # partially quoted word
'/foo'* # mixture of quotes and globs
'/a \\ "\ ' # single quotes treat everything literally
# missing end quotes
'abc
"def
# backslash at end of line
a\
```

Some of those are just syntax errors, but at least RPM needs to report the error properly.
