It would be convenient to have an 'rfind' method equivalent to the 
string one; the only (slow, wasteful) alternative I can find is taking 
slices of the mmap, or using successive seek/read, followed by 
rindex.

The best way of seeing an rfind() method would be to
implement it and submit a patch.  (Otherwise it's a feature
request, and processing bugs usually takes precendence over
implementing features.)

Moving to the RFE tracker.

Attached patch adds two things: an 'end' argument to find, and an
'rfind' method. This includes minimal tests for rfind, but as I actually
refactored find and rfind into a single method, tests covering find also
cover most of rfind :).  I added 'end' first because the refactoring
seemed more natural (symmetric?) after that. Also included are updated
docs, and NEWS.
