Hm. I have no strong opinion about whether this looks better or not;
people who write more Perl than I do ought to weigh in.
However, I do want to note that we've chosen the shorter style for
the catalog .dat files, and that's enforced by reformat_dat_file.pl.
I'd be against changing that decision, because one of the goals for
the .dat file format was to minimize the risk of patches applying in
the wrong place. Near-content-free lines containing just "{" or "},"
would increase that risk by reducing the uniqueness of patch context
lines.
It's not essential for the .dat files to match the Perl layout we use
elsewhere, of course. But perhaps consistency is one factor to
consider here.
