I'm frightened!

Rename detection is O(n^2), so when it looks like it will take a really
long time, we skip it. This has been happening for a while, but 1.5.5
only recently started telling the user (based on some people wondering
why renames weren't found during their enormous merges).

The default rename limit is 100, but you can bump it via the
diff.renamelimit config option. A few tests that I did imply that
200-400 is reasonable for logging, and 800-1000 for a merge:

Are you running into actual problems with rename detection, or is the
message just too scary and confusing?
