The whole submoduleAlternateErrorStrategyDie item is interpreted as
being part of the supporting content of the preceding item. This is
because we don't give a double-colon "::" for the separator, but just a
single colon, ":". Let's fix that.
There are a few other matches for [^:]:\s*$ in Documentation/config, but
I didn't spot any similar bugs among them.
