Having just pulled the latest updates, git describe says:
v1.5.6.3-315-g10ce020
Why does it think there are 315 commits on top of the v1.5.6.3 tag?
Short answer. Because there are. Count'em ;-)
$ git rev-list v1.5.6.3..master | wc -l
A longer answer. v1.5.6.X releases are from 'maint'. The branch has
forked from the mainline loooong time ago (at v1.5.6, to be exact), and
has only fixes. 'master' is a separate branch for development that would
eventually lead to the next major release (planned to be v1.6.0).
