Subject: [PATCH] stagit-index: Add -r flag to preserve repo paths

I want subdirectories in my stagit installation:

    user1/repoa
    user2/repob
    user2/repoc
    ...

However, the current implementation truncates the links in the index
to be the basename of the repo.

This patch adds a new flag, -r, which prints the repodir's as they were
passed on the commandline instead of the basenames to the index.
