Обсуждение: pgsql-server: Add missing null terminator to escaped string; clean up

Add missing null terminator to escaped string; clean up unnecessarily
obscurantist coding conventions.

    pgsql-server/src/bin/initdb:
        initdb.c (r1.58 -> r1.59)
        (http://developer.postgresql.org/cvsweb.cgi/pgsql-server/src/bin/initdb/initdb.c.diff?r1=1.58&r2=1.59)

Thanks.  Wonder why my testing worked?  I guess xmalloc was giving me
zeroed memory.

One-shot programs like initdb are very likely to see all-zeroed memory,
since that's what the kernel gives you.  It's only after you start
freeing things that you'll get nonzero areas from malloc ...
