Author: emaste Date: Fri Nov 2 21:20:46 2018 New Revision: 340083 URL: https://svnweb.freebsd.org/changeset/base/340083 Log: newvers.sh: fix git false positive -dirty tag Assuming that any output from `git diff-index --name-only` implies changes in the working tree results in false positives: files with metadata, but not content, changes are also listed. Check that content differences exist before adding the -dirty tag to the git hash.
