From d82f33e20dcf068e679eff2a16ecf8fe7b10fb31 Mon Sep 17 00:00:00 2001 From: Stephan Beyer Date: Fri, 25 Jul 2008 18:28:41 +0200 Subject: Move launch_editor() from builtin-tag.c to editor.c launch_editor() is declared in strbuf.h but defined in builtin-tag.c. This patch moves launch_editor() into a new source file editor.c, but keeps the declaration in strbuf.h.
