Actually it's not quite right: on seeing "CP20866", vim falls back to
iso-8859-1. While this works on the surface, as it's just another
8-bit charset, things like case conversion or detecting word
boundaries might be incorrect.
Anyway, here's a fix that doesn't involve a translation table:
* libc/locale/nl_langinfo.c (nl_langinfo): Fall back to
__locale_charset only if the current locale does not specify a
charset.
