LYNX-DEV LYCgi.c patch for CGI programs which wait for close of input

[Mark H. Wilkinson]

I've noticed that some CGI programs wait for their standard input to
be closed when processing posted forms. The LYCgi.c code doesn't do
this: it reads the results before closing its end of the pipe. The
simple fix is included below.

-Mark.
