[oe] Naming/Version conventions for git/svn recipes

[Andreas Mueller]

I did not find this in documentation. What is the preferred convention for PV/PR. Up to now I saw:

Option 1:
PV = "1.3.8+git${SRCREV}"
PR = "r0"

Option 2:
PV = "1.1.0"
PR = "${INC_PR}.0"
PR_append = "+git${SRCREV}"

Is there a preferred convention?
