What if we do simple substitution for occurrences of ["[", "]"] with a space, along with the error message. If not that, then just puke out the error and exit rather than ignore the entry. That will force it to be fixed. In my case I accidentally forgot to edit them out when copy/pasting the entry from an emerge complaint about needing that to satisfy some other pkg. If it was ignored, I would be incensed wondering why it keeps giving me the same use complaint after I already added it (although incorrectly) to package.use.
