Well, the above is the "optimum case".  It actually passed through a
2.16.0 state.

Maybe it's more realistic to just omit the -S option and look at the
whole history of a snippet.

The point is to see at which point of time the snippet stopped being
declared fit for 2.16.  Let's say that it was commit
13da8b27aabc5d5a752d00ed1e2b99ad20f0f264, so we want the one before
that, appending a ~1 to the commit id.  You can then use something like

git show 

to get that snippet.  If it isn't at all in Documentation/snippets/new,
then it should convert cleanly with convert-ly (unless that snippet just
continued to compile but stopped doing what it should, and nobody
noticed so far in our documentation).
