[bug#27865] [PATCH 2/3] pull: Fetch source code from Git.

[Mathieu Othacehe]

Hi Ludo,

Nice job ! Error code handling in git is really a welcome addition too
:)

> +    ((? integer? error)                           ;old Guile-Git
> +     (leave (G_ "Git error ~a~%") error))
> +    ((? git-error? error)                         ;new Guile-Git
> +     (leave (G_ "Git error: ~a~%") (git-error-message error)))))

If an old Guile-Git (without error support) is used git-error? and
git-error-message won't be available anyway, so it is really necessary
to test for an integer ?

I'll use the same piece of code in Cuirass soon.

Thanks,

Mathieu
