Fix the public interface function el_getc(3).
On OpenBSD, the effects are to set the return argument to the NUL byte
in case of a read failure (for robustness) and to properly set errno
when the character is out of range and cannot be stored in a byte.
Once we enable UTF-8, this will be needed to avoid returning bogus
bytes for valid Unicode characters.
On systems where the internal representation of wchar_t doesn't
match UCS-4, breakage was potentially even worse.
OK czarkoff@.
