  4. Subject: [PATCH] Fix swapping fake lines in pch_swap
  5. * src/pch.c (pch_swap): Fix swapping p_bfake and p_efake when there is a
  6. blank line in the middle of a context-diff hunk: that empty line stays
  7. in the middle of the hunk and isn't swapped.
  8. Fixes: https://savannah.gnu.org/bugs/index.php?53133
