Thank you. I applied the patch with the tweaks below.

I removed the ".git" suffix

I slightly reworded this part, which looks very odd, to say the least.

I removed this part of the description, since it is a detail of
implementation.

For future patches, please avoid inserting the package definition at the
end of the file, as this is more likely to introduce merge conflicts.
You wouldn't want to make my life miserable, would you ? ;)
