71	skip 404 process for fastcgi_intercept_errors	www.google.com/accounts/o8/id?id=AItOawnA1VZSCGBObt9MGuZNyHKljvkW-zBDNko	somebody	"when fastcgi_intercept_errors off (default):
1. php program have error (but display_errors off in php), it got http 500 status, and display a blank page.
2. php program offer it's own 404 error page (http status 404), it work fine.

when fastcgi_intercept_errors on:
1. php program have error (but display_errors off in php), it got http 500 status, redirect to error_page for error 500 (not blank page).
2. php program offer it's own 404 error page (http status 404), it will also redirect to error_page for 404, (not the one generated by upstream program).

we want nginx don't redirect 404 for such case the program already offer it's 404 page, just redirect other error.

this patch will add a new option fastcgi_intercept_error_skip_404 to skip the 404 status for fastcgi_intercept_errors on.
