| An update: i've compiled the shell again, linked against libedit
| as of today (master branch, 493ac26f0cdccc, [Add mvts(4) driver

Yet another update.
I've #defined DEBUG_READ in libedit and actually found my problem.
The reason why the german umlauts don't appear is that they actually
result in "ed-unassigned" errors because of the input-to-command map.
I'm using multi-platform multi-shell init scripts which i've just
recently updated to be compatible to some pretty ancient
Bourne-compatible shell, and now it turns out that the plain
FreeBSD /bin/sh is classified as "NONE" type at all, so that no
set command is used to configure shell behaviour upon startup. I
didn't think about this before, hmm.
Anyway, once the login shell starts, it's a vanilla shell, but
with emacs mode enabled, or at least this is what the '$ set -o'
says which then also turns over all the ED_UNASSIGNED to ED_INSERT
commands. If nobody jumps into this here i'll try to figure out
why, how and where that actually happens and fix it, maybe next week.
