I found this bug comes from the definition of WHITESPACE
characters in pg_ctl.c. WHITESPACE is defined as folows:
   #define WHITESPACE "\f\n\r\t\v"
In fact, WHITESPACE does not contain whilespace (0x20) :-(
I attach a patch to fix it.

BTW, I also found similar definitions in some places.
(Please grep with "\t\n\r".)
They are a bit different from each other.
For example, whitespaces is defined as " \t\n\r" in tzparser.c.
Is it ok in the inconsistency? Or, should we always use " \f\n\r\t\v" ?
