for-each-ref will ask git >= v1.9

[bkcsoft]

Heck, even GitLab requires git 2.8.4 so I think we should be fine bumping from git 1.9 😂

[cez81]

No, it should be ok for earlier versions. At least from https://git-scm.com/docs/git-for-each-ref/1.4.4

[lunny]

@bkcsoft I mean we should document it.

[bkcsoft]

@lunny Version requirements must be documented yes. But we should also have a init()-function that verifies and panic() if requirements are not meet.

Please rebase and add the version check.

Please rebase and add the version check.

Rebased but I don't think adding version check is needed. Like I said earlier for-each-ref has existed from as early as at least 2006 (git/git@9f613dd#diff-6d644249e994f8d938b2d2313b7a12e1). Git version required for this function will be < version required for the module.
