I'm not sure what to do with a translation marked "review requested", but I've tested the options dialog with the French translation. The strings look fine (to me, not native French speaker!), but some of the access keys are not in the strings so they appear in brackets at the end. Also, many are vowels, which isn't recommended in English at least.
You may use the translation if you want (just like you may use partial translations if a translator e.g. quits or misses an update), but my experience is that if someone requests a review, he/she isn't really ready to release it just yet. To be on the safe side, you can always PM/e-mail the translator and ask about it. And if you find any inconsistencies or peculiarities, PM about them too (there are several developers that do just that, checking the translations for e.g. access key conflicts).
You could also ask one of the French translators that frequent this site if he/she would be kind enough as to review the translation in question.
