[bitbake-devel] [PATCH] fetch2/repo.py: improve unpack to copy only asked project.

[Nicolas Cornu]

From: Nicolas Cornu <n.cornu at overkiz.com>

Today this fetcher copy the whole repo projects in each sub-project.

This patch is not here to be merged, but to have review on it.
The problem is that if your google-repo got 150 projects, and you want to build each with a specific recipe, sources
will be copied for each.
