+Subject: [PATCH] revparse: fix parsing bug for trailing `@`
+
+Origin: https://github.com/libgit2/libgit2/commit/c9d31b711e8906cf248566f43142f20b03e20cbf
+
+When parsing a revspec that ends with a trailing `@`, explicitly stop
+parsing. Introduce a sentinel variable to explicitly stop parsing.
+
+Prior to this, we would set `spec` to `HEAD`, but were looping on the
+value of `spec[pos]`, so we would continue walking the (new) `spec`
+at offset `pos`, looking for a NUL. This is obviously an out-of-bounds
+read.

+Subject: [PATCH] index: correct index has_dir_name check
+
+Origin: https://github.com/libgit2/libgit2/commit/eb4c1716cd92bf56f2770653a915d5fc01eab8f3
+
+`has_dir_name` is used to check for directory/file collisions,
+and attempts to determine whether the index contains a file with
+a directory name that is a proper subset of the new index entry
+that we're trying to add.
+
+To determine directory name, the function would walk the path string
+backwards to identify a `/`, stopping at the end of the string. However,
+the function assumed that the strings did not start with a `/`. If the
+paths contain only a single `/` at the beginning of the string, then the
+function would continue the loop, erroneously, when they should have
+stopped at the first character.
+
+Correct the order of the tests to terminate properly.
