psql: Fix invalid memory access

Due to an apparent thinko, when printing a table in expanded mode
(\x), space would be allocated for 1 slot plus 1 byte per line,
instead of 1 slot per line plus 1 slot for the NULL terminator.  When
the line count is small, reading or writing the terminator would
therefore access memory beyond what was allocated.
