Or even "last displayed sal" :-)

This is why we like periods at the end of each ChangeLog bit - this
looks like
it got cut off... plus it's good to say as "Declare." as reminder that it's
not a code bit that was added.

I'm not going to be persnickety about this one, but we really want
random comment
fixups to be separate patches - took me a moment to decide if this was
somehow
relevant to the masses of code.

I would lose the rhetorical question, it's not really adding much.

No mass-delete by omitting the argument??

I'm not clear on why we need gdbarch, since CORE_ADDR should always be
long enough?

Ah, for address printing. My inclination is to say to drop this
admirable goal and make a separate patch that attempts to be smart for
address printing in breakpoint and skip lists in general. It seems like
a nice design might look at actual values in the list and only use wide
space if all addresses are large, sort of like how html table layout works.

"Not skipping"
In general, it's looking pretty good! As people have commented
previously, regexp would be nice to have, but with this much code, I
think it's better to get a first version in, accumulate a little
practical experience before deciding about which additional features to
add. (Between Moz and GCC, there are going to be lots of users I think.
:-) )
Also, in thumbing back through old discussion, I notice that the last
state was that you had submitted paperwork for copyright assignment, but
not received anything, and I don't remember getting any email adding you
to the "has assignments" list. Did you ever get the confirmation from
the FSF?
