I do understand why we would want merge_strategies_one_file() helper
introduced by this step so that the helper can work in an arbitrary
repository (hence taking a pointer to repository structure as one of
its parameters).

But the "merge-one-file" command will always work in the_repository.
I do not see a point in using helpers that can work in an arbitrary
repository, like repo_read_index() or repo_hold_locked_index(), in
the above.  I only see downsides --- it is longer to read, makes
readers wonder if there is something tricky involving another
repository going on, etc.

Write a wrapper around strtol(...,...,8) to reduce repetition, and
make sure you do not pass NULL as the second parameter to strtol()
to always check you parsed the string to the end.

Here, as I said above, it is perfectly fine to pass
the_repository().

Likewise, I do not see much point in saying the_repository->index; the_index
is a perfectly fine short-hand.

These functions we see above all are now easy to write these days,
thanks to the previous work that built many helpers to perform ommon
operations (e.g. remove_path()).  Reusing them is very good.

The original only checked if ret is zero or non-zero; here we
require ret to be large.  Intended?  

ll_merge() that called ll_xdl_merge() (i.e. the most common case)
would return the value returned from xdl_merge(), which can be -1
when we got an error before calling xdl_do_merge().  xdl_do_merge()
in turn can return -1.  The most common case returns the value
returned from xdl_cleanup_merge(), which is 0 for clean merge, and
any positive integer (not clipped to 127 or 128) for conflicted one.

Style. (cf. Documentation/CodingGuidelines).

If open() fails, we write to a bogus file descriptor here.

What is the error returning convention around here?  Our usual
convention is that 0 signals a success, and negative reports an
error.  Returning the value returned from add_file_to_index() below,
and error() above, are consistent with the convention, but this one
returns 1 that is not.  When deviating from convention, it needs to
be documented for the callers in a comment before the function
definition.

Prepare three char [] buffers and use oid_to_hex_r() instead,
instead of relying that we'd have sufficient number of entries in
the rotating buffer.
