From: Edwin Kofler <edwin@kofler.dev>
The function `__git_eread`, that reads the first line from the file, calls the `read` builtin without passing the flag option `-r`. When the `read` builtin is called without the flag `-r`, it processes the backslash escaping in the text that it reads. We usually do not want to process backslashes of the input but want to read the raw contents.
To make it read the first line as is, pass the flag `-r` to the `read` builtin in the function `__git_eread`.
