* The first form returns a diff between the index and the current working

* +diffable+ can either be a +Rugged::Commit+ or a +Rugged::Tree+.
*

* directory or the +diffable+ will be used for the "new file" side.
*
* The following options can be passed in the +options+ Hash:
*
* :paths ::
* An array of paths / fnmatch patterns to constrain the diff to a specific
* set of files. Also see +:disable_pathspec_match+.
*
* :max_size ::
* An integer specifying the maximum byte size of a file before a it will
* be treated as binary. The default value is 512MB.
*
* :context_lines ::
* The number of unchanged lines that define the boundary of a hunk (and
* to display before and after the actual changes). The default is 3.
*
* :interhunk_lines ::
* The maximum number of unchanged lines between hunk boundaries before the hunks
* will be merged into a one. The default is 0.
*
* :reverse ::
* If true, the sides of the diff will be reversed.
*
* :force_text ::
* If true, all files will be treated as text, disabling binary attributes & detection.
*
* :ignore_whitespace ::
* If true, all whitespace will be ignored.
*
* :ignore_whitespace_change ::
* If true, changes in amount of whitespace will be ignored.
*
* :ignore_whitespace_eol ::
* If true, whitespace at end of line will be ignored.
*
* :ignore_submodules ::
* if true, submodules will be excluded from the diff completely.
*
* :patience ::
* If true, the "patience diff" algorithm will be used (currenlty unimplemented).
*
* :include_ignored ::
* If true, ignored files will be included in the diff.
*
* :include_untracked ::
* If true, untracked files will be included in the diff.
*
* :include_unmodified ::
* If true, unmodified files will be included in the diff.
*
* :recurse_untracked_dirs ::
* Even if +:include_untracked+ is true, untracked directories will only be
* marked with a single entry in the diff. If this flag is set to true,
* all files under ignored directories will be included in the diff, too.
*
* :disable_pathspec_match ::
* If true, the given +:paths+ will be applied as exact matches, instead of
* as fnmatch patterns.
*
* :deltas_are_icase ::
* If true, filename comparisons will be made with case-insensitivity.
*
* :include_untracked_content ::
* if true, untracked content will be contained in the the diff patch text.
*
* :skip_binary_check ::
* If true, diff deltas will be generated without spending time on binary
* detection. This is useful to improve performance in cases where the actual
* file content difference is not needed.
*
* :include_typechange ::
* If true, type changes for files will not be interpreted as deletion of
* the "old file" and addition of the "new file", but will generate
* typechange records.
*
* :include_typechange_trees ::
* Even if +:include_typechange+ is true, blob -> tree changes will still
* usually be handled as a deletion of the blob. If this flag is set to true,
* blob -> tree changes will be marked as typechanges.
*
* :ignore_filemode ::
* If true, file mode changes will be ignored.
*
* :recurse_ignored_dirs ::
* Even if +:include_ignored+ is true, ignored directories will only be
* marked with a single entry in the diff. If this flag is set to true,
* all files under ignored directories will be included in the diff, too.
