Super nit: "flag_descriptions.*" would sound better.

We're not doing it for the other source files... so I think we should keep
consistency unless we decide to change all of the entries.

I think agrieve@ meant I keep "flags" singular: "flag_descriptions", not that I
should use '*' instead of file endings.

Oops, I did indeed misread that comment. :)

Done.
