Fixes #2578

`\d` in sed regular expressions doesn't work (see http://stackoverflow.com/questions/14671293/why-does-d-doesnt-work-in-regular-expression-in-sed)

Merged from #2906

The function `git_prompt_info` calls `git config` for its stdout output,
but doesn't handle the stderr output.  This can lead to problems,
e.g. if the git config file is unreadable for some reason (permissions
etc).

This fixes the issue by simply ignoring the stderr output.
