diff parser: match the header order of hg diff --git patches

The output might look like:

  diff --git a/A b/B
  old mode 100644
  new mode 100755
  rename from A
  rename to B
  --- a/A
  +++ b/B

Such files were shown as 'modified binary file chmod 100644 => 100755' without
diff.

Now the chmod and diff will be shown ... but still not the rename.

Correct parsing of headers do require a better parser - one do not just use a
regexp.
