Macros
#define	N_DIFF_COMMON 0
	the line is present in both texts
#define	N_DIFF_CONTEXT_FULL ((size_t)-1)
	n_diff_to_unified() context asking for every common line, without hunk headers
#define	N_DIFF_DELETE 1
	the line is only in the first text
#define	N_DIFF_INSERT 2
	the line is only in the second text
#define	N_DIFF_MAX_EDITS_CEILING 4000
	hard ceiling n_diff_lines() clamps max_edits to, keeping the worst case trace under about 64 MB
#define	N_DIFF_MAX_EDITS_DEFAULT 1000
	n_diff_lines() default ceiling on the number of differing lines searched
#define	N_DIFF_NO_LINE ((size_t)-1)
	N_DIFF_LINE line_a / line_b value when the line has no counterpart there.

Functions
N_DIFF_RESULT *	n_diff_lines (const char text_a, const char text_b, size_t max_edits)
	Compare two texts line by line.
void	n_diff_result_free (N_DIFF_RESULT **result)
	Free an edit script and every line it holds.
N_STR *	n_diff_to_unified (const N_DIFF_RESULT *result, size_t context)
	Render an edit script as unified diff text.
