[pacman-dev] [PATCH] makepkg: Use a recursive, shallow clone for git://

[Drew DeVault]

makepkg: Use a recursive, shallow clone for git://

This clones git submodules, which are required to build most projects
that use them. This change is harmless for packages that don't use them.

This also modifies the initial clone to use --depth=1, which avoids
checking out the entire history and saves some bandwidth and improves
the time required to clone.
