 ================================================================
 
+Alternatively, run `make vcxproj` and then load the generated `git.sln` in
+Visual Studio. The initial build will install the vcpkg system and build the
+dependencies automatically. This will take a while.
+
+Instead of generating the `git.sln` file yourself (which requires a full Git
+for Windows SDK), you may want to consider fetching the `vs/master` branch of
+https://github.com/git-for-windows/git instead (which is updated automatically
+via CI running `make vcxproj`). The `vs/master` branch does not require a Git
+for Windows to build, but you can run the test scripts in a regular Git Bash.
+
+Note that `make vcxproj` will automatically add and commit the generated `.sln`
+and `.vcxproj` files to the repo. This is necessary to allow building a
+fully-testable Git in Visual Studio, where a regular Git Bash can be used to
+run the test scripts (as opposed to a full Git for Windows SDK): a number of
+build targets, such as Git commands implemented as Unix shell scripts (where
+`@@SHELL_PATH@@` and other placeholders are interpolated) require a full-blown
+Git for Windows SDK (which is about 10x the size of a regular Git for Windows
+installation).
+
+If your plan is to open a Pull Request with Git for Windows, it is a good idea
+to drop this commit before submitting.

+# Testcase 13e, directory rename in virtual merge base
+#
+# This testcase has a slightly different setup than all the above cases, in
+# order to include a recursive case:
+#
+#      A   C
+#      o - o
+#     / \ / \
+#  O o   X   ?
+#     \ / \ /
+#      o   o
+#      B   D
+#
+#   Commit O: a/{z,y}
+#   Commit A: b/{z,y}
+#   Commit B: a/{z,y,x}
+#   Commit C: b/{z,y,x}
+#   Commit D: b/{z,y}, a/x
+#   Expected: b/{z,y,x}  (sort of; see below for why this might not be expected)
+#
+#   NOTES: 'X' represents a virtual merge base.  With the default of
+#          directory rename detection yielding conflicts, merging A and B
+#          results in a conflict complaining about whether 'x' should be
+#          under 'a/' or 'b/'.  However, when creating the virtual merge
+#          base 'X', since virtual merge bases need to be written out as a
+#          tree, we cannot have a conflict, so some resolution has to be
+#          picked.
+#
+#          In choosing the right resolution, it's worth noting here that
+#          commits C & D are merges of A & B that choose different
+#          locations for 'x' (i.e. they resolve the conflict differently),
+#          and so it would be nice when merging C & D if git could detect
+#          this difference of opinion and report a conflict.  But the only
+#          way to do so that I can think of would be to have the virtual
+#          merge base place 'x' in some directory other than either 'a/' or
+#          'b/', which seems a little weird -- especially since it'd result
+#          in a rename/rename(1to2) conflict with a source path that never
+#          existed in any version.
+#
+#          So, for now, when directory rename detection is set to
+#          'conflict' just avoid doing directory rename detection at all in
+#          the recursive case.  This will not allow us to detect a conflict
+#          in the outer merge for this special kind of setup, but it at
+#          least avoids hitting a BUG().
