git to darcs broken in multiple ways

[jgoerzen]

This is with 0.9.23.

I am using tailor to convert a Linux kernel repo over to darcs.

After awhile, I see:

12:57:22 [I] [Ok]

    e.action_kind = action_map[state[0]]
KeyError: 'C'

If I try to re-run git at this point, it will migrate a couple of changesets over, but eventually die at what appears to be a rename.

My config is:

[DEFAULT]
verbose = True

[project]
target = darcs:target
start-revision = INITIAL
root-directory = /home/jgoerzen/work/git2/work
state-file = tailor.state
source = git:source
subdir = .

[git:source]
repository = /home/jgoerzen/work/git2/linux-2.6
branch=master

[darcs:target]
repository = /home/jgoerzen/work/git2/linux-2.6-darcs

Fixed markup.

I looked at git documentation, and as I supposed that 'C' stands for "Copied". Given that tailor does not support COPY events, I think that the backend should convert those to ADD events, like the svn backend does.

But to fix the thing a proper description of the line emitted by "git-diff-tree" is needed.

Here is diff-tree output:
