Use "diff -ur file.c.orig file.c" to get a context patch of a single file, or to get
one patch of several files, run your diff on directories:  "diff -urN pcb.orig pcb"

To get the spring mass function to appear in the Select menu, you just
need to add one line:

--- gui-top-window.c.orig	2005-03-28 15:17:57.169543507 -0600
+++ gui-top-window.c	2005-03-28 15:21:33.410754513 -0600

It will use the <control>s shortcut you've specified in your SpringMassSelected
GtkActionEntry, but what about <alt>s to avoid taking away the default change
size <control>s?
