Recover the complicated situation after my bad merge
I made a mistake merge.  Reverting it in c778945806 undid the state
on master, but now I realize it crippled the git merge mechanism.
As the merge contained a mix of commits from `master..staging-next`
and other commits from `staging-next..staging`, it got the
`staging-next` branch into a state that was difficult to recover.

I reconstructed the "desired" state of staging-next tree by:
 - checking out the last commit of the problematic range: 4effe769e2
 - `git rebase -i --preserve-merges a8a018ddc0` - dropping the mistaken
   merge commit and its revert from that range (while keeping
   reapplication from 4effe769e2)
 - merging the last unaffected staging-next commit (803ca85c20)
 - fortunately no other commits have been pushed to staging-next yet
 - applying a diff on staging-next to get it into that state

longDescription =
'' Brotli is a generic-purpose lossless compression algorithm that
compresses data using a combination of a modern variant of the LZ77
algorithm, Huffman coding and 2nd order context modeling, with a
compression ratio comparable to the best currently available
general-purpose compression methods. It is similar in speed with
deflate but offers more dense compression.
The specification of the Brotli Compressed Data Format is defined
in the following internet draft:
