From 89d21f4b649d5d31b18da3220608cb349f29e650 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 17 Apr 2005 11:39:18 -0700 Subject: Move "parse_commit()" into common revision.h file. This also drops the old-style date parsing. We just don't care enough, since we dropped that format pretty early. Yes, this could do with some cleanup, and a common library file.
