cmdutil: templating keywords latesttag and latesttagdistance This can be used for referring to revisions in a reasonable meaningful, stable and monotonically increasing way, suitable for releases or builds directly from a repository. The latest tag is found by searching through untagged ancestors and finding the latest tagged ancestor based on tag date. The distance is found from the length of the longest path to the tagged revision. For example: hg log -l1 --template '{latesttag}+{latesttagdistance}\n' can return 1.3.1+197 This is mostly work by Gilles Moris <gilles.moris@free.fr>
