debugger-make-xrefs in lisp/emacs-lisp/debug.el adds a cross reference
to the first symbol name of each line in the debugger's *Backtrace*
buffer (if that symbol name is the name of a function and the lisp
source file in which it was defined can be located). Lines of frames
that are set to debug on exit are marked with a `*'.
debugger-make-xrefs considers this `*' the first symbol name on the
line and consequently does not add any cross reference. What about
the following patch to fix this?
Lute.
