Urk. You're making another copy of that string, simply to transform it
into an svn_string_t structure. Icky. (ooh, and it gets worse...)

Ideally, qval would reside on the stack, and you could:

  qval.data = tmp->data;
  qval.len = tmp->len;

Obviously, that will change the other branch, but I imagine you can figure
out how to do that :-)

Hmm. Now that I pulled up the file to really look at the context, I'd
recommend changing qval to a 'const char *'. You can then do:

  qval = tmp->data;

and in the other branch:

  qval = svn_base64_encode_string(value, pool)->data;

Then just write out "qval" rather than "qval->data".

Cheers,
