svn commit: r1548689 - /subversion/trunk/subversion/libsvn_diff/parse-diff.c

New Revision: 1548689

URL: http://svn.apache.org/r1548689
Log:
Remove dead code from svn_diff_hunk_readline_diff_text().

Since the hunk header will never be included in the hunk->diff_text_range
there is no reason to try to deal with reversing it.

* subversion/libsvn_diff/parse-diff.c
  (svn_diff_hunk_readline_diff_text): Remove some always false conditional
    code and a variable it used.
