Hello,

I was looking through your patch. It seems good, the of the functions 
was very similar.
I have a question for you. What was the reason to replace 
"printfPQExpBuffer" by "resetPQExpBuffer" and "appendPQExpBufferStr"?

Thank you for attention!

Indeed. I guess that it was initially a copy paste.

Because the "printf" version implies interpreting the format layer which 
does not add significant value compared to just appending the string.
