Care to share problems with Pasky and I to take a look at,
please?

I agree.  I got really disgusted when I tentatively pulled the
current Git.xs into "next" and installed it for my own use to
notice that it broke git-fmt-merge-msg hence git-pull workflow.

Pasky, can we first iron out kinks in the build procedure and
installation before converting existing programs further?  The
things I worry about currently are:

 - the SITELIBARCH gotcha I sent you a message about (and you
   responded to it already -- was that an Acked-by?);

 - RPM target -- we probably acquired a new build-dependency in
   which case the .spec file needs to be updated;

 - Make sure Git.xs builds and installed result works fine on
   all platforms we care about, including Cygwin and other
   non-Linux boxes.

I'd even suggest we revert the changes to git-fmt-merge-msg to
keep it working for now, until the above worries are resolved.
Otherwise we cannot have it in "next" safely (and I REALLY _do_
want to have Git.pm infrastructure in "next" soonish).

We can start using Git.xs and friends in some _new_ ancillary
programs, once we solve building and installing problems for
everybody.  That way it would help us gain portability and
confidence without disrupting existing users.
