[PATCH v2 1/4] config --show-origin: report paths with forward slashes

[Johannes Schindelin <johannes.schindelin@gmx.de>]

On Windows, the backslash is the native directory separator, but all
supported Windows versions also accept the forward slash in most
circumstances.

Our tests expect forward slashes.

Relative paths are generated by Git using forward slashes.

So let's try to be consistent and use forward slashes in the $HOME part
of the paths reported by `git config --show-origin`, too.
