This gives a better sense of the version of the binary as it can be mapped to a particular revision or release of Git itself. For example: $ make && ./git-remote-persistent-http -print_label 2.9.1.275.g75676c8 Discussion of this patch is available on a related thread in the mailing list surrounding this package called "contrib/persistent-https: update ldflags syntax for Go 1.7+".
