    • Minor fixes, cleanups, and clarifications · 145e696b
      There are three actual changes in this commit:
      
      1. When the trailing newline of a file is removed in a diff, the
         change will now be reported with `GIT_DIFF_LINE_DEL_EOFNL` passed
         to the callback.  Previously, the `ADD_EOFNL` constant was given
         which was just an error in my understanding of when the various
         circumstances arose.  `GIT_DIFF_LINE_ADD_EOFNL` is deprecated and
         should never be generated.  A new newline is simply an `ADD`.
      2. Rewrote the `diff_delta__merge_like_cgit` function that contains
         the core logic of the `git_diff_merge` implementation.  The new
         version doesn't actually have significantly different behavior,
         but the logic should be much more obvious, I think.
      3. Fixed a bug in `git_diff_merge` where it freed a string pool
         while some of the string data was still in use.  This led to
         `git_diff_print_patch` accessing memory that had been freed.
      
      The rest of this commit contains improved documentation in `diff.h`
      to make the behavior and the equivalencies with core git clearer,
      and a bunch of new tests to cover the various cases, oh and a minor
      simplification of `examples/diff.c`.

    • Update diff to use iterators · 74fa4bfa
      This is a major reorganization of the diff code.  This changes
      the diff functions to use the iterators for traversing the
      content.  This allowed a lot of code to be simplified.  Also,
      this moved the functions relating to outputting a diff into a
      new file (diff_output.c).
      
      This includes a number of other changes - adding utility
      functions, extending iterators, etc. plus more tests for the
      diff code.  This also takes the example diff.c program much
      further in terms of emulating git-diff command line options.

    • Continue implementation of git-diff · a2e895be
      * Implemented git_diff_index_to_tree
      * Reworked git_diff_options structure to handle more options
      * Made most of the options in git_diff_options actually work
      * Reorganized code a bit to remove some redundancy
      * Added option parsing to examples/diff.c to test most options

    • Clean up diff implementation for review · 3a437590
      This fixes several bugs, updates tests and docs, eliminates the
      FILE* assumption in favor of printing callbacks for the diff patch
      formatter helpers, and adds a "diff" example function that can
      perform a diff from the command line.
