I see one code omission - the changes to session.cxx don't look complete. You
updated the regular constructor, but not the copy constructor for the
systemtap_session class.
In general it seems odd to have both session->prologue_searching and
session->prologue_searching_mode. I'd think you'd get rid of
session->prologue_searching and make "-P" a synonym for
"--prologue-searching=always". Also, you'll have to be careful with
ENABLE_PROLOGUES.
