There are two things the the index does better than MQ:

1. The ability to add only certain changes to a file (qrefresh only
supports adding everything)
2. The ability to incrementally increase or decrease the stuff that is
contained in the changes:

suppose i made changes to all files a, b, c, ..., z, but my changeset
should contain only a,c,f,h,j,l,n,q and t.

I now do "qref a c f h j l q t" (note that i forgot "n")

If I notice it right away, I cannot write something like "hg qref +n",
i have to list every file again "qref a c f h j l n q t", the chance
being not small that I again forget a different file (and when the
file names are actually long paths instead of single letters, it gets
even harder to check that you did not forget anything)
