[PATCH 0/5] RFC: for_each_revision() helper

 Hi,

 [This' also a git-send-email test, so, if this fail by showing just
  the first e-mail in the series, do not blame me :)]

 This series introduces a helper macro to help programs to walk through
revisions (details on the first patch).

 Shawn has already alerted me that some people don't like to
'hide C constructs', but I think that in this case it's useful, as explained
in the next e-mail.

 The complete diff stat is:

 But if we subtract the for_each_revision() macro's code we get:

 4 files changed, 7 insertions(+), 14 deletions(-)
