make Save-As/Displayed/All-Packets save not only the displayed packets but
also any other packets needed (e.g., for reassembly) to fully dissect the
displayed packets.
This works only for the "All packets" case; choosing only the Selected packet,
the Marked packets, or a range of packets would require actually storing which
packets depend on which (too much memory) or going through the packet list many
times (too slow). Also, this behavior is always the case: you can't save the
displayed packets without their dependencies (I don't see why this would be
desirable).
So far this is done for SCTP and things using the reassembly routines (TCP has
been tested).
The Win32 dialog was modified but hasn't been tested yet.
One confusing aspect of the UI is that the Displayed count in the Save-As
dialog does not match the number of displayed packets. (I tried renaming the
button "Displayed + Dependencies" but it looked too big.) The tooltip tries
to explain this and the fact that this works only in the All-Packets case;
suggestions for improvement are welcome.
Implementation details:
Dissectors (or the reassembly code) can list frames which were needed to
build the current frame's tree. If the current frame passes the display
filter then each listed frame is marked as "depended upon" (this takes up the
last free frame_data flag).
When performing a Save-As/Displayed/All-Packets then choose packets which
passed the dfilter _or_ are depended upon.

allocate them to be large enough.
Add checks that the numbers in the range fit in a guint32.
Check the validity of a range before saving or printing, and report
errors in an alert box.
Clean up white space.

really more of an Ethereal/Tethereal component than a libethereal
component (nothing else in libethereal knows about capture files); move
it back out of libethereal. (The range stuff doesn't; we leave it in
libethereal.)
