Lib-ify fmt-merge-msg
In builtin.h, there exists the distinctly "lib-ish" function fmt_merge_msg(). This function can currently only be called by built-in commands but, unlike most of the other functions in the header, it does not make sense to impose this restriction as the functionality can be logically reused in libgit. Extract this function into fmt-merge-msg.c so that related definitions can exist clearly in their own header file. While we're at it, clean up #includes that are unused. This patch is best viewed with --color-moved. Signed-off-by: Denton Liu <liu.denton@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
