Ah, that's showing just the mergeinfo stored at the top of the tree.
propget on the contrib dir shows the appropriate mergeinfo:
```
$ svn propget svn:mergeinfo -r337810 contrib/lua
/vendor/lua/dist:326353-337809
```

however this still isn't particularly useful for inferring the
merge-from rev in a git revision because 337809 represents the
repository revision at the time the merge was done, but we really care
about the last revision in /vendor/lua/dist at the time of that merge.

I think this is the appropriate merge-from revision:
```
$ svn log -l 1 ^/vendor/lua/dist@337809
