First, rewinding head to replay your work on top of it...


That will be better if this
2b541e2bbd23ab5c375c4ce1e0fae5255470a5e7 to 2c17d767934f7f6784d2e0411c7a3a9bfc9c4d08
will be replaced by this
2b541e2bbd23ab5c375c4ce1e0fae5255470a5e7..2c17d767934f7f6784d2e0411c7a3a9bfc9c4d08

This will allow us to copy/paste this string into 'diff' command
git diff 2b541e2bbd23ab5c375c4ce1e0fae5255470a5e7..2c17d767934f7f6784d2e0411c7a3a9bfc9c4d08

In compare to first version it give error:
git diff 2b541e2bbd23ab5c375c4ce1e0fae5255470a5e7 to 2c17d767934f7f6784d2e0411c7a3a9bfc9c4d08
fatal: ambiguous argument 'to': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'

Thank you.
