[bug-cflow] Extended version of cflow-mode.el

[John Sturdy]

I've written some extensions to cflow-mode.el, using
outline-minor-mode to toggle hiding of subtrees, and adding "next" and
"previous", "next at same level", "previous at same level", and "up a
level" commands.  By default, these show the functions referenced in
another window, narrowed to just the function, with space and delete
scrolling the other window and moving to the next / previous function
on reaching the bottom / top.  If you've hidden a subtree, when you
reach the end of the subtree that contains it,  you can be given the
chance to reveal and move to that subtree (or it can do it
automatically).  The "next" and "previous" commands normally skip
recursive calls.  The overall effect ist that you can start at the top
of a cflow file, and just keep pressing space, to read through the
program in execution order but skipping bits which, if you stick to
that order, you will have already seen.

I've attached cflow-mode.el and cflow.texi to this message -- will
resend if the list manager strips attachments.
