Your log message documents this change as 'This way, the hash parser's error
message is preserved.', which is not what this change does.
Before and after this change the message was preserved, but now a different
error code is returned; that is a different kind of change.
Personally I would have also changed the line above this to something like:
err = svn_error_compose_creater(err, svn_stream_close(stream));
To avoid dropping more error details than necessary.
See also below for a behavior change, that also applies here.

Same thing applies here.

The quick wrap code, does the same wrapping as the svn_error_createf(). It just
explicitly doesn't alter the error code.
*and* more importantly it doesn't return an error if the inner error is not an
error after all.
So this change changes the code from potentially returning NULL, to always
returning an explicit error.
(Whether this is a good thing or not, requires a more closely review of te
surrounding code)
