In which case, ACK and pushed.

Your original patch was (mistakenly) attributed to 
<soulxu at soulxu-ThinkPad-T410.(none)>, which is not a valid address; you 
should probably fix your ~/.gitconfig settings on that computer. 
Hopefully I was correct in re-attributing authorship to the email you 
used for previous patches.
