Thanks, committed.

Hmm. If you've piped stdout somewhere else, that produces a spurious
empty line in stderr:
$ bin/initdb -D data-foo > /dev/null
initdb: input file "/home/heikki/pgsql.master/share/postgres.bki" does
not belong to PostgreSQL 9.5devel
Check your installation or specify the correct path using the option -L.
initdb: removing data directory "data-foo"
I think the newline needs to go to stdout instead.
But in any case, that's just one error out of many similar ones that can
happen during initdb. If we care enough to fix this, we should fix them
all. Not sure it's worth the churn, though, unless you can come up with
some kind of a simple wholesale solution, rather than adding
fprintf(stdout, "\n") calls to every error condition.
