As we found out with I88751ed6df7d5f9dad735171e19f82dea745b4da and the resulting downtime, cgit does not like multi-line description values. The cgit(5) man page is conspicuously quiet on quoting or multi-line values; let's just ensure we don't do this again. This does detect the newlines in the original change.
