From: Edwin Kofler <edwin@xxxxxxxxxx>
The function `__git_eread`, which 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. For this reason, it is
generally considered the best practice to always use the `read`
builtin with flag `-r` unless one intensionally processes the
backslash escaping. For the present case in git-prompt.sh, in fact,
all the occurrences of the calls of `__git_eread` intend to read the
literal content of the first lines.
To make it read the first line literally, pass the flag `-r` to the
`read` builtin in the function `__git_eread`.
