encoding.c: handle needmore error from rb_enc_precise_mbclen()
rb_enc_ascget() erroneously reports success even if the given byte
sequence is incomplete, for non-ASCII compatible encoding strings.
rb_enc_precise_mbclen() may return a negative value on error, and thus
rb_enc_ascget() must not store the return value in 'unsigned int';
otherwise the subsequent MBCLEN_CHARFOUND_P() check won't catch the
error. [ruby-core:78646] [Bug #13034]
