So here's my take on it (on top of the two-patch series I just sent).
Dave's patch is 3rd here, just to show its rebased form, but do not take
that as a final endorsement. I still think it could use tests, but I
will let him write them. I am just doing the cleanup in the area, none
of which needs to be his problem. :)

  [1/3]: cmd_push: set "atomic" bit directly
  [2/3]: cmd_push: pass "flags" pointer to config callback
  [3/3]: push: allow --follow-tags to be set by config push.followTags
