[bitbake-devel] [RFC PATCH 2/5] bb.fetch.git: truncate branches to SRCREV

[Christopher Larson]

From: Christopher Larson <chris_larson at mentor.com>

Rather than keeping the commits between SRCREV and the branch HEAD, point the
remote branch at the SRCREV, so no commits after SRCREV are kept. If the user
needs them, a git fetch will pull them down.
