+# Testcase 12f, Rebase of patches with big directory rename
+# Commit O:

+# dir/subdir/tweaked/{f,g,h,Makefile_SUB_O}
+# dir/unchanged/<LOTS OF FILES>
+# Commit A:
+# (Remove f & g, move e into newsubdir, rename dir/->folder/, modify files)
+# folder/subdir/{a,b,c,d,Makefile_TOP_A}
+# folder/subdir/newsubdir/e_A
+# folder/subdir/tweaked/{h,Makefile_SUB_A}
+# folder/unchanged/<LOTS OF FILES>
+# Commit B1:
+# (add newfile.{c,py}, modify underscored files)
+# dir/{a,b,c,d,e_B1,Makefile_TOP_B1,newfile.c}
+# dir/tweaked/{f,g,h,Makefile_SUB_B1,newfile.py}
+# dir/unchanged/<LOTS OF FILES>
+# Commit B2:
+# (Modify e further, add newfile.rs)
+# dir/{a,b,c,d,e_B2,Makefile_TOP_B1,newfile.c,newfile.rs}
+# dir/tweaked/{f,g,h,Makefile_SUB_B1,newfile.py}
+# dir/unchanged/<LOTS OF FILES>
+# Expected:
+# B1-picked:
+# folder/subdir/{a,b,c,d,Makefile_TOP_Merge1,newfile.c}
+# folder/subdir/newsubdir/e_Merge1
+# folder/subdir/tweaked/{h,Makefile_SUB_Merge1,newfile.py}
+# folder/unchanged/<LOTS OF FILES>
+# B2-picked:
+# folder/subdir/{a,b,c,d,Makefile_TOP_Merge1,newfile.c,newfile.rs}
+# folder/subdir/newsubdir/e_Merge2
+# folder/subdir/tweaked/{h,Makefile_SUB_Merge1,newfile.py}
+# folder/unchanged/<LOTS OF FILES>
+#
+# Notes: This testcase happens to exercise lots of the
+# optimization-specific codepaths in merge-ort, and also
+# demonstrated a failing of the directory rename detection algorithm
+# in merge-recursive; newfile.c should not get pushed into
+# folder/subdir/newsubdir/, yet merge-recursive put it there because
+# the rename of dir/subdir/{a,b,c,d} -> folder/subdir/{a,b,c,d}
+# looks like
+# dir/ -> folder/,
+# whereas the rename of dir/subdir/e -> folder/subdir/newsubdir/e
+# looks like
+# dir/subdir/ -> folder/subdir/newsubdir/
+# and if we note that newfile.c is found in dir/subdir/, we might
+# overlook the dir/ -> folder/ rule that has more weight.
