config: Keep inner whitespace verbatim

Configuration values are expected to be quoted when they have leading or trailing whitespace, but inner whitespace should be kept verbatim even if the value is not quoted. This is already documented in git-config(1), but the code caused inner whitespace to be collapsed to a single space, breaking, for example, clones from a path that has two consecutive spaces in it, as future fetches would only see a single space.
