Prevent closing a NULL pinfo handle

I confess to not having a clue what is really going on here, but I'm
seeing the following errors from a CVS build (yes, I know debugging has
been turned on), and it looks like this would be the right thing to do:

CloseHandle(moreinfo->myself_pinfo) 0x0 failed
child_info_spawn::~child_info_spawn():125, Win32 error 6

	* child_info.h (~child_info_spawn): Prevent closing a NULL handle.

Although, I suspect if the correct thing to do were that simple, it would
already have been noticed and fixed?  And yes, I know that functionally
this doesn't make much difference.
