help: I broke test-gendoc-ro.t and I have no idea how

[Augie Fackler]

With my pager-modernization work applied, I've got one test failure that is blocking me from mailing:
augie% make test-gendoc-ro.t
cd tests && python run-tests.py -j16 test-gendoc-ro.t
--- /usr/local/google/home/augie/Programming/hg/crew/tests/test-gendoc-ro.t

ERROR: test-gendoc-ro.t output changed

This is caused by something I did in https://hg.durin42.com/hg-wip/rev/b7285db7c604, but I have no idea what. Can anyone help me figure out this last problem?

Thanks!
Augie
