environment.con commit sha1_file.c: cleanup hdr usage (d65a16f)
   1/*
   2 * We put all the git config variables in this same object
   3 * file, so that programs can link against the config parser
   4 * without having to link against all the rest of git.
   5 *
   6 * In particular, no need to bring in libz etc unless needed,
   7 * even if you might want to know where the git directory etc
   8 * are.
