Hi Alan,
Yes, you are completely correct :-) Posted one thing but unintentionally
took a "shortcut" when producing the backtrace (not a smart thing to do
when trying to get people to repro...).
Here's the backtrace when doing doing M-% foo <RET> bar <RET> (note that
it's still 0, 1 not 0, 3!):
Debugger entered--Lisp error: (args-out-of-range #<buffer test.cc> 0 1)
buffer-substring-no-properties(0 1)
perform-replace("foo" "bar" t nil nil nil nil nil nil nil nil)
query-replace("foo" "bar" nil nil nil nil nil)
funcall-interactively(query-replace "foo" "bar" nil nil nil nil nil)
call-interactively(query-replace nil nil)
command-execute(query-replace)
Thank you for your help!
Best,
Jayden
