[PATCH 1/2] Export relative path handling "prefix_path()" function

From: Linus Torvalds <torvalds@osdl.org>
Date: Aug 17, 2005, 20:31 UTC
Message-ID: <Pine.LNX.4.58.0508171331060.3553@g5.osdl.org>

Not all programs necessarily have a pathspec array of pathnames, some of them (like git-update-cache) want to do things one file at a time. So export the single-path interface too.
