From e78d5d49935373dabcc40c5e32aefe4956a70b97 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Fri, 8 Jul 2016 05:12:55 -0400 Subject: use write_file_buf where applicable There are several places where we open a file, write some content from a strbuf, and close it. These can be simplified with write_file_buf(). As a bonus, many of these did not catch write problems at close() time.
