Patch attached (it compiles, but I haven't tested it thoroughly). This
should fix two bugs in xdisp.c and a bug in Fend_of_line.

All of these bugs were silently fixed by my pos_t conversion.

At the very least, FETCH_CHAR should be renamed so it's clear that the
right way to use it is FETCH_CHAR (bytepos), not FETCH_CHAR (charpos).
I suggest FETCH_CHAR_AT_BYTEPOS.
