Rework the backtrace handling Try and improve the print-backtrace-and-exception/knots output, be selective about the stack frames which are shown to try and produce some useful output which reflects user code and hide the &knots-exceptions. This commit also introduces a bunch of tests scripts that produce output from print-backtrace-and-exception/knots, to help test this code in different situations. 2026-03-20 19:11:03 +00:00			`(use-modules (knots))`

Remove Guile line numbers from backtrace tests As these differ between 3.0.10 and 3.0.11. 2026-03-22 19:12:59 +00:00			`;; FIRST BACKTRACE ENTRY: (with-exception-handler`
