From 30d6c6eabfefed330bebbed9126fe21bf349fd6b Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Fri, 21 Feb 2014 17:32:05 +0100 Subject: [PATCH] sha1_file_name(): declare to return a const string Change the return value of sha1_file_name() to (const char *). (Callers have no business mucking about here.) Change callers accordingly, deleting a few superfluous temporary variables along the way.
