[ragel-users] Is it safe to modify the buffer on which a Ragel-generated FSM is operating?

In an action, can I safely modify the part of the input buffer prior
to the the current position p?  I'm doing so currently, and it seems
to work just fine, but I want to confirm that this is a behavior I can
count on (due to the generated code inherently not requiring
backtracking) rather than an implementation detail that might change
in future Ragel releases.
