patch: enable meld to recognise all git status codes

[Tom Scytale <scytale gmail com>]

running recent versions of meld on my git repository has been failing with this traceback:

  File "/usr/local/lib/meld/meld/task.py", line 112, in iteration

    ret = next(task)

  File "/usr/local/lib/meld/meld/vcview.py", line 447, in _search_recursively_iter

    self.vc.cache_inventory(rootname)

  File "/usr/local/lib/meld/meld/vc/_vc.py", line 275, in cache_inventory

    self._tree_cache = self._lookup_tree_cache(directory)

  File "/usr/local/lib/meld/meld/vc/git.py", line 348, in _lookup_tree_cache

    self._update_tree_state_cache("./", tree_state)

  File "/usr/local/lib/meld/meld/vc/git.py", line 324, in _update_tree_state_cache

    columns = self.diff_re.search(entry).groups()

AttributeError: 'NoneType' object has no attribute 'groups'

This is because meld does not recognise the full set of status codes output by `git diff-index` - the regex used does not recogise the 'T' or 'X' codes. This patch fixes this.
