Robin Roth 281398fdc2 fix git switch branches in combination with depth on old git versions (#3492) ... * fix git switch branches in combination with depth * the old implementation is correct, but relies on git working correctly (as only newer versions do) * with some older git version (e.g. 1.8.3), git fetch remote branch does not work, if the branch does not yet exist locally * this patch works around that without explicitly checking the git version * future refactoring is needed to reduce the number of fetches to a minimum; but this patch makes the code "correct" * add git version requirements to doc * replace set-branches with git 1.7.1 compatible version		2016-12-08 11:24:20 -05:00
