OK, I've made a patch which fulfills this requirement pretty well.
Hopefully you'll find it reasonably clean and unintrusive:

    https://github.com/aspiers/kitenet-mr/commit/b9a4e45aefe87c11ade1e4c4022e511f0d96d53c

With this patch, if you have .mrconfig files defining repositories:

    [path/to/foo]
    ...

    [path/to/bar]
    ...

then you can limit mr to only act on those via:

    mr -r foo,bar $action

If there is a clash of directory names, then it can be resolved via a
new special parameter 'name':

    [path/to/foo]
    checkout = git clone ...
    name = foo.git

    [path/to/a/different/foo]
    checkout = cvs checkout ...
    name = foo.cvs

and then you can do:

    mr -r foo.cvs update

etc.
