We should also keep in mind that such logs aimed at users should support i18n - unlike the existing dumps for compiler developers, which are quite properly English only, and most calls to internal_error which should only appear if there is a compiler bug and are also only meant to be useful for compiler developers (so represent useless work for translators at present - though it does seem possible some internal_error calls could actually appear with invalid input rather than compiler bugs and so should be normal errors).
We should first support i18n of C++ error messages, which is totally broken for languages that have more than one case or more than one article form (e.g. singular and plural of "the").
