Hi Kushagra,

Thanks for the patches! A couple of remarks on your patches before I
dive into the code:

1. Please merge your changes into fewer, more logical patches. Making
small patches when working locally is a good idea, but when you submit
them for merging, they should be reorganized into logical changes. In
the case of your patches, one adds the new function, and the next
patch removes it. We don't need this in the git history.
2. Your patches have trailing whitespace in them. Please configure
your editor to either alert you about this, or fix it silently. Most
good text editors have these features. You can even configure your Git
to complain if you try to commit anything with whitespace errors.
Trailing whitespaces can be a major pain when merging larger patches
or branches in the future.
3. A good patch would also contain a test case that fails before. but
passes after the patch is applied. This way we can verify the
correctness of the patch and ensure that no regressions occur in the

Apart from these, the build failed on Travis with the --without-ssl
configure option. That is an issue worth looking into.
The other two builds on travis failed inside the multi-byte locale
tests. It's probably some subtle bug, but we'll have to fix that as

The code itself looks good. Will provide a deeper review once the
larger, more obvious issues have been sorted.
