language.properties determines which langueages to show in the Select Languages dialog, langGroups.properties determines which default character encoding to use for each language.
These changes haven't made it to the 1.8 branch yet:
Bug 347632 patches regionNames.properties as well, which has l10n impact, so it's too late for that.

Requesting approval. The original patches all had r=jshin and blanket sr=roc (for intl properties files)
