From: Junio C Hamano Date: Tue, 29 Sep 2009 06:40:08 GMT Subject: [PATCH 1/2] builtin-mailinfo.c: check error status from rewind and ftruncate Message-ID: <1254206409-13256-1-git-send-email-gitster@pobox.com> A recent "cut at scissors" implementation rewinds and truncates the output file to store the message when it sees a scissors mark, but it did not check if these library calls succeeded.
