Good idea in principle.

When we have a designed error message, we present one--and, there, brevity
is good.
But backtraces are for developers only anyway, and are not designed error
messages.
So for backtraces I'm against throwing *anything* of the backtrace
message away because we don't know what part of it is important (if we
did, we'd print a designed error message instead--I'm all for doing that).
I think this is something the default Guile setting gets wrong and I
don't understand how it can be a good idea to suppress half of a
message intended to simplify debugging for a developer "because it's
too long". The length is nothing compared to the amount of text a
developer has to type in order to reproduce the missing parts later on,
if it's even possible.
I'm even actually using core files (including attaching to them using a
debugger in order to examine variable values), so I might be an outlier.
So I'd be for either presenting the entire backtrace or suppressing the
entire backtrace, not having teaser backtraces :)
