How would you interpret: hg  revert -r 43, as 43 might as well be a 
filename?

First check if 43 is not the name of a file? This doesn't sound robust 
to me.

Maybe we should take a different approach:
  hg revert --only r,a
or
  hg revert --only modified

(i.e. use additions, removals and modified as keywords, and
interpret prefixes of those keywords as well)
