@jkorous-apple Got it. I agree that it would be better to move the comments to
the header. Will land it soon. Thanks!

I see your concern. Would you just consider moving the annotation to header
file then? It looks more like documentation of public interface than
implementation details to me. I imagine any programmer interested in these
methods needs to know these details so they

Thanks @jkorous-apple for the comment. I think your suggestion is a more
precise description for the implementation, and adjusted the comments
accordingly.
I intentionally didn't add the details to the comments for the header,
as LL

Thank you for your patience @twoh and sorry for the delay.
I have few suggestions about doxygen annotations but otherwise LGTM.

@jkorous-apple Thanks for the comments! Yeah, I was thinking of
O(lenght_of_string) approach, but considering the complicatedness of the
implementation (I guess the real implementation would be a bit more complex
than your pseudo implementation to handle quote and '\n\r' '

I am sorry I wasn't really clear. What I meant was to do something like this
(pseudo-code, dealing only with newlines):
if( Str.size() == 0)
return;
// Calculate all the extra space needed first.
typename T::size_type extra_space = 0;

Thanks @jkorous-apple for your comments. I modified the type for the variables
and replaced unnecessary inserts and erases with updates.

Wouldn't **auto** or **typename T::size_type** instead of **unsigned** be more
appropriate here

Addressing @vsapsai's comments. Thank you for the suggestion! Added test case
actually finds an off-by-one error in the original patch. I improved the
comments as well.

On the first glance string erase and insert seem to be done correctly. But we
can still improve the tests. Can you please add tests for tricky cases where
new line or backslash appear in unexpected places? Some of the examples are

R"ab
