If any of the files read by __git_eread have \r\n line endings, read will only strip \n, leaving \r. This results in an ugly prompt, where instead of

    user@pc MINGW64 /path/to/repo (BARE:master)

the last parenthesis is printed over the beginning of the prompt like

    )ser@pc MINGW64 /path/to/repo (BARE:master
