Thanks! Looks like the reflowing changed in one of the test files, this should be easy to fix.

You are welcome!

I had a short glimpse at it, but wasn't able to resolve that issue immediately.
@jgm: Can you step in please? I'm not familiar with the project internals at all, so feel free to take this task over. Adding another commit that resolves the issue is highly appreciated!

Easiest way to fix it is:

make TESTARGS=--accept

Then git diff to make sure the changes look right.

I edited the file right in GH, let's see if it checks now.
