From 46ce8b6d2a88b67a839fb53bfa0b8849215352b5 Mon Sep 17 00:00:00 2001 From: Julian Phillips Date: Tue, 13 Feb 2007 01:21:39 +0000 Subject: [PATCH] Allow fetch--tool to read from stdin If the reflist is "-" then read the reflist data from stdin instead, this will allow the passing of more than 128K of reflist data - which won't fit in the environment passed by execve.
