From 3eefc189172b88dece6fb6d479b3ed13cc483dbc Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Tue, 18 Apr 2006 16:45:27 -0700 Subject: Tentative built-in format-patch. This only does --stdout right now. To write into separate files with pretty-printed filenames like the real thing does, it needs a bit mroe work.
