Re: Stdio.Buffer, need a way to revisit old positions in the output

Also, on a somewhat related note, add_hstring() can take an array with
things to add as it's first argument.

This is however only of use if you need to add chars, strings and
buffers, but not integers (and other internal hstrings), since there
is no way to add integers (add_int*) using this unless you have the
integers as subbuffers or strings, which does not seem to be a good
way to achieve performance.
