Re: print -v with multibyte characters

[Jun T <takimoto-j@xxxxxxxxxxxxxxxxx>]

In the case of 'print -v var', args[] are RE-metafied at line 4871
(builtin.c), but the length len[] is not updated.

At line 4959,
        fwrite(*args, *len, 1, fout);
this metafied args[] are written to buf with the wrong length len[].

I think args[] should not have been RE-metafied at line 4871, because
without '-v var' args[] are no metafied at this fwrite().

We need to metafy buf for setsparam(), as the current code wrongly
does at line 4981.
