[PATCH] parse-diff.c condition for unrecognized lines

[Daniel Shahaf]

Is the following patch correct?

         {
           /* git patches can contain an index line after the file mode line */
           if (!starts_with(line->data, "index "))

It passes tests.

On the patch-exec branch, I will use this patch to support diffs that
have both mode changes and tree changes: on such diffs, the condition is
evaluated on the "copy to" line (so 'state == state_git_tree_seen'
holds), and the "new mode" line had set 'line_after_tree_header_read' in
a prior iteration (so the condition as a whole holds).

Cheers,

Daniel
