This is a test repo for libgit2 where tree entries have type changes

Types
-----

The key types that could be found in tree entries are:

1. GIT_FILEMODE_NEW             = 0000000 (i.e. file does not exist)
2. GIT_FILEMODE_TREE            = 0040000
3. GIT_FILEMODE_BLOB            = 0100644
4. GIT_FILEMODE_BLOB_EXECUTABLE = 0100755
5. GIT_FILEMODE_LINK            = 0120000
6. GIT_FILEMODE_COMMIT          = 0160000

I will try to have every type of transition somewhere in the history
of this repo.
