Thanks for handling this. I was terribly busy with internal stuff and had no
time to check all my emails. Usually if one continues someone else patches,
it is a good practice to somehow credit the original author in the final
patch.

If changes are small, I usually keep the original authorship and only add
note before my signoff (see commit 855ed04a3758b205e84b269f92d26ab36ed8e2f7
for the example). When the whole code has been rewritten, modified or 
heavily
extended, I changed authorship and added respective note to the commit 
message
(see commit e8d9d1f5485b52ec3c4d7af839e6914438f6c285 for such example). Feel
free to use any of those styles.
