odd output in initdb

I saw some odd pgstat output during an initdb on Windows today:

The files belonging to this database system will be owned by user
"pgrunner".
This user must also own the server process.

The database cluster will be initialized with locale C.
The default database encoding has accordingly been set to SQL_ASCII.
The default text search configuration will be set to "english".

Success. You can now start the database server using:

"C:\msys\1.0\home\pgrunner\bf\root\HEAD\inst\bin\postgres" -D "data"
or
"C:\msys\1.0\home\pgrunner\bf\root\HEAD\inst\bin\pg_ctl" -D
"data" -l logfile start

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the -A option the
next time you run initdb.

A little searching on the buildfarm shows this started around Jan 10th:

pgbfprod=# select min(snapshot) from build_status_log where sysname
= 'red_bat' and log_stage = 'initdb.log' and log_text ~ 'pgstat';
min

I can't see an obvious culprit in the commit logs right off. Does anyone
have an idea what's going on?
