pgsql: Make pg_bsd_indent add a space between comma and period.

Make pg_bsd_indent add a space between comma and period.

Formatting of variadic functions and struct literals with named fields
used to be ugly due to pg_bsd_indent treating period as always being a
binary operator. After a comma, it's not that, so insert a space.

Bump pg_bsd_indent's version so that people who use out-of-tree
copies will know they need to update. (This also covers the other
pg_bsd_indent behavioral change introduced in a3e6beba6.)
