strip -f doesn't exist?

[j w]

Running:
    hg help strip

Gives:
    hg strip [-f] [-b] [-n] REV
    ...

Yet when I try to use 'strip -f', I get:
    hg strip: option -f not recognized

I want to strip a revision even though I have local changes. Is this
not allowed for some reason? If so, the commandline docs should be
updated.
Or even better, it would be nice if strip -f worked.

I'm using v1.0.1 via Windows binary installer - I can check more
recent when I get home...

What I'm really trying to accomplish is to turn an mq patch into local changes.
So I do:
    hg qpush foo
    hg qdel -rfoo
    hg update -r-2
    hg revert -rtip --all
(now I have local changes from the foo patch)
    hg strip -f tip

Is there a better way (one that works) ?
