jpg: treat EOF as EOI marker
...
Some jpegs, rightly or wrongly, do not contain an EOI marker. This
causes jpg(1) to bail out even after correctly parsing the entire
image.

fix dangerous werrstr() usages
...
werrstr() takes a format string as its first argument.
a common error is to pass user controlled string buffers
into werrstr() that might contain format string escapes
causing werrstr() to take bogus arguments from the stack
and crash.
so instead of doing:
werrstr(buf);
we want todo:
werrstr("%s", buf);
or if we have a local ERRMAX sized buffer that we can override:
errstr(buf, sizeof buf);

jpg: center image in screen
...
when using the jpg(1) programs interactively, draw the
image in the center of it. this avoids wasting space
with always on borders on small windows and looks better
when used in fullscreen.
