Crash on hexediting empty file

[Leonard den Ottolander <leonard den ottolander nl>]

Hi,

Try F3 -> F4 -> F2 on an empty file. Boom, ouch. (Might be that if you
still are in edit mode you need to try after getting back in view mode.)

Happens with an (apart from acinclude.m4) unpatched version from a
couple of days ago (20060129), but also with a patched (but not with
acinclude.m4) version a couple of weeks old (20051207).
