When your shell sees a `...` construct, it takes the text between the
backticks, executes it as a comand and replaces the source text and the
backticks with the output that command sent to its standard output
stream. For the `git rev-list` command, this is the SHA-1 name of a
commmit.
When the shell sees a $(...) construct, it does with the text between
the opening "$(" and the closing ")" and treats it almost the same way
it does for the `...` construct (the exact differences are of no
interest here).
So what happens here is that you ask the shell to interpret the SHA-1
name of a commit found by the `git rev-list` command as another command.
There is no point doing that.
