[patch] 7.4 initdb - drop trailing slash from $PGDATA

I made a mistake while running 7.4 under W2k/Cygwin, so perhaps
the patch would give user a little more comfort.

root@w2kpicasso:~/work/tpu/course/1132/sql/postgres# LC_ALL=C initdb /usr/share/postgresql/data/
The files belonging to this database system will be owned by user "root".
This user must also own the server process.

The database cluster will be initialized with locale C.
