Repo conversion procedure is basically done

[<es...@th...>]

I can now produce a git version of the GNUPLOT repository with the
following properties:

(1) Content correctness, as previously discussed.

(2) All committer fields are full DVCS-style IDs.

(3) Over 3100 other authorship attributions are recovered from
    ChangeLog files.

(3) The faq module contents is merged in.

(4) Three very early releases that servived only as tarballs are
    glued to the tail of the repository.

(5) An annotated tag marks the comversion point.

I think this is basically done, unless Ethan wants me to glue more
tarballs to its tail.  It looks pretty good in gitk.

I'm appending the current version of my conversion script.
Stakeholders should read it carefully to check my assumptions.

# Convert the gnuplot CVS repository.  Results go in gnuplot

# Requires the repository head version of reposurgeon.
# The following archaic release tarballs must also be present:
# gnuplot-1.10A.tar.gz
# gnuplot-2.0.tar.gz
# gnuplot-3.5.tar.gz
