Inclusionary patterns: -I

The `-I` flag serves as an "undo" for the `-e` pattern. It overrides any
matching exclusions, allowing for temporary
listing/installation/removal.

For example, if you want to try a `.pythonrc` but leave it in your
`EXCLUDES` in rcrc(5), you can do:

    rcup -Ipythonrc pythonrc
