From 5332b2af104180b8135e0b3528ace7596cb9ba09 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Sun, 25 Feb 2007 23:36:10 +0100 Subject: diff: support reading a file from stdin via "-" This allows you to say echo Hello World | git diff x - to compare the contents of file "x" with the line "Hello World". This automatically switches to --no-index mode.
