[Buildroot] [PATCH] support/download: relocate the git clone comment

[Yann E. MORIN <yann.morin.1998@free.fr>]

Baruch, All,

On 2015-05-28 14:35 +0300, Baruch Siach spake thusly:
> Following commit 95a572282e87 (pkg-infra: move the git download helper to a
> script, 2014-07-02), move the comment describing the shallow clone trickery as
> well. Merge this comment with the existing helper comment that was added in
> 7e40a1103a91 (support/download: convert git to use the wrapper, 2014-08-03).
> 
> Rename $($(PKG)_DL_VERSION) to ${cset} to match the helper code context.
> 
> Cc: "Yann E. MORIN" <yann.morin.1998@free.fr>
> Signed-off-by: Baruch Siach <baruch@tkos.co.il>

Acked-by: "Yann E. MORIN" <yann.morin.1998@free.fr>

Regards,
Yann E. MORIN.
