One bug in my version: loclen+1 should be loclen+modlen+1. Without
changing that, the pathname gets truncated if @mod is used. Otherwise
it seems to work.
One separate but related problem I noticed while testing is that
musl's locale name length limit of 16 is insufficient for something
like "en_GB.UTF-8@euro". If we want to allow users to have an explicit
".UTF-8" in the locale name (which, as we discussed a while back,
users may want to do if they plan to ssh into glibc-based systems)
then we should probably increase this limit a bit, perhaps to 24 or
so.
