Robert Abel 041fe8fc83 git-prompt: fix reading files with windows line endings ...

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

This patch fixes the issue by changing the internal field separator
variable IFS to $'\r\n' before using the read builtin command.

Note that ANSI-C Quoting/POSIX Quoting ($'...') is supported by bash
as well as zsh, which are the current targets of git-prompt, cf.
contrib/completion/git-prompt.sh.
