initdb Did Not Escape the Password

Dear all,

    The initdb seems did not escape (PQescapeString) the password.  The
following is my test result, with password: ab'ds)24

imacat@atlas ~ % initdb -D /tmp/postgres -E utf8 --locale=en_US.utf8 -U postgres -W
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale en_US.utf8.

    I have attached a patch that seems to solve this issue.  It works
for me.  Please tell me if there is any problem.
