RE: exception from inside false-if-exception?

[Attila Lendvai]

apparently this has been fixed between 3.0.9 and HEAD. i've wasted my time 
chasing a ghost...

can we please have a new release? :)

as a sidenote, i also had some broken expectations in my test.scm.

it's a tangential, but namely, when #:unwind #t then the handler in a w-e-h 
returns from the w-e-h block, but with #:unwind #f it tries to return to the 
RAISE that raised the condition. i.e. a lousy little keyword arg (usually a 
page down) fundamentally changes the behavior of w-e-h. yet another surprise 
that violated my expectations regarding APIs.

anyway, i've attached a patch that clarifies what's happening for anyone who 
stumbles upon this; i.e. be clearer that (?) a backtrace is printed due to 
reaching a continuation barrier.

this makes it grep'able, and if the user also prints a backtrace, then it makes 
it clear that it's something printed by guile.

if someone wants to investigate further, then i'm also attaching a new version 
of my test.scm that behaves in an unexpected way on 3.0.9, but not on HEAD 
(more specifically on guile-next in guix, which is a rather recent commit).

HTH,
